It depends on your intended audience. For my money, I wouldn't put curses in just for the sake of being edgy or mature, but if it seems absolutely natural for a character to use them then I'd prefer to see them in. And avoiding them can seem unnatural, though that may depend on the individual character, some might conscientiously avoid swearing while another might swear like a sailor.
Depending on the setting (such as fantasy or science fiction unattached to our world) you might use invented curses. Though this can also seem forced or unnatural, depending on how well you do it.
There's one interesting solution I saw in the sitcom Father Ted, which allowed a great deal of foul language before the water shed by taking advantage of the character's Irish accents. "Feck."
Well, it depends on what sort of comic you're making: if it's the sort of gritty, realistic story then yes, swearing will be part of it because it happens. If it is comedy or something light and fluffy you can still have the F bomb but kinda censor it very obviously so it gets double comedic effect. If it is for kids, no. If it is for teens go ahead, they have more imaginative cusswords anyway! aaand if it is fantasy or scifi you can invent your own frak-word.
Again you might have heard of this, but it depends on what your story is. The setting the mood and the characters will define your story, so if its about lets say a young latina girl with a back pack with her monkey friend who wears boots then cussing would be a no. If its about a group of sailors on shore leave in a third world country trying to have their way with the local women, well you know where I'm getting at right?
If you are paying, Curse. If you are getting paid, Sit and pant at any order. Personally i try to write without swearing... but sometimes the story gets better with people swearing like kindergartners around an alcoholic father.
I think that if your story matter is already adult, then swearing is fine... like if you have any nudity or suggestive talk etc, then not adding in swear words might seem weird. I think you should just define your audience you are aiming at before asking this question. Is it young adult? Some not-so-harsh swearing is fine. Is it young adult + kids? No swearing. 18+? Swearing.
This question depends entirely on the tone of the work and the intended audience. If it's meant to be a very light-hearted work, or intended for children or "all ages," you should omit curse words. In any other circumstances, however, you should use them. In the real world, people swear when they feel it is appropriate. Most stories I know of involve people in rather trying situations, and in that case it may be more jarring for them to not swear. Not to mention that what people consider to be "appropriate" cause to swear is highly variable, and can tell your readers something about there character. A person who never swears, regardless of the circumstances (or, heaven forbid, uses only minor oaths like "Gosh darnit to heck!) is probably going to be some sort of stuck-up, austere, overtly-moral character (a preacher, perhaps). On the other hand, a person who swears frequently shows a lack of discipline and concern for their outward appearance (like a thug, or a common laborer). Beware of the latter case, though. Verisimilitude can actually come off as distasteful, when it comes to swear words. In the real world, I know a few good-for-nothings who use "fucking" like a discourse particle: "It's like, you know, fucking..." Usage to that extent is grating on the nerves.
When I was in highschool, I had very clean language in my stories because I was afraid people would disapprove. My mom, who is not that into literature, read one of my stories, and said, "Sweetie, just write for the characters. If they have to use bad language, that's what you need to write." Best advice ever. As long as you're true to the characters, you have no one to answer to.
Consider your target audience unless just writing for your friends. Certain words are really frowned on unless only for adult viewing. Others are acceptable in the teen range. I think you can look up profanity by age rating. Words like damn and crap are more acceptable than the f bomb and sh** for example. They are just considered tamer. Heck, pick up a book or two and check them out. Nothing like real time examples. Past that I can't say if you should cut out all curse words or not. It's up to you and your characters. I think you'll find that even the X-Men and Spidey have the word "damn" every once in a while. Dr Strange said "crap". So research and feel your way through.
I wouldn't take curse words out to the point where it's unrealistic. Is everyone in your story Mormon and conservative? Then maybe.
But realistically, I think SOMETIMES people swear. You don't need it constantly, but removing "Shit" and replacing it with "Darn it!" seems forced and unrealistic..depending on the character. But generally, if your character is not religious or burdened with an overly heavy conscience, they'll swear at some point.
It's up to you in the end. It's YOUR comic, not everyone else's. I'm making a comic as well, and there is going to be swearing in it as well as nudity, because that's what I want. Do what you want and you will always be happy.
It depends on what you are writing and your goals with it. However, at the least keep in consideration that you aren't writing what you would say, but what you're characters are saying. If it is or isn't typical that the character would say that, then that's how you have to write it. I would say if you do have dialogue with profanity that you just write it full out, because 9 times out of 10 a story with profanity is serious enough that ephemizing it comes off badly. With exception, eppamism can be done, but only of the way you are intending it to be read is as a beqrudging curse, as if the character is swearing but doing so under their breath, or not really wanting to , or by mistake. But again it's situation based on the story.
That was sort of my thinking as well. I don't intend to have a curse word every 3 words or anything but at times things like "What in the world?!" or "Darn it!" seem to take me out of the story because it seems like the writer is trying so hard to avoid even a minor curse word.
As I suspected, I'm getting as many answers as there are people.
In addition to what SparkliPrincess said, I would also consider the character's personality. I have some characters that would swear at just about anything because that's how they are, and others who would think twice before saying curse words. Take real life for example: A child raised around people who swear a lot will absorb that and grow up not thinking anything of it, and it'd just come out of their mouth naturally; whereas, a child who lived in a family who watched out for their language and he/she wasn't used to hearing it would probably not find themselves just saying it just because it's natural to them.
