Well, Evil isn't necessarily about the action as much as it is about crossing a line.

When the character thinks: "By doing harm to others I can make my life better" they are tempted with evil, no matter what the action is, they are looking over that line and considering crossing it. I think you should emphasize that instead of the action that follows. Give the character a moment to reflect on the choice and then consciously make the choice.

Taking a sandwich isn't evil; it's just mean and/or an act of selfishness.
Threatening the father is mean, but only evil if the character realizes the extent of how it will affect others and does it anyways.
If you want to keep it kid friendly, you can side-step the idea that the father could be killed and think of the result as being hurt.
(You don't always need to side-step death as a topic for children (some fairytales are really blood drenched), but children see death abstractly, so massive amounts of blood are not necessary, but if you treat it as something terrible a single death can get across a lot more fear than thousands. )

All that to say, I don't think the clone should do anything more serious than threaten to hurt someone as his first act of evil, but once the audience knows that this character has consciously chosen their own desires over the safety and wellbeing of others, readers won't as easily know where this character will stop in pursuing their selfish desires.

The father confronts the clone.

Feeling annoyed at being harassed, the clone picks up the father, realizing how easy it would be to just toss him over into the alligator pit.

The clone thinks about the consequences for a minute as the child begs him to put his father down.

The clone decides that the father and anyone else wouldn’t dare bother him if he tosses him into the pit. The father looks frightened and the child is crying.

The hero stops the clone from tossing him into the pit, the clone drops the frightened father back on the ground. The child rushes his father out of the way as the hero fights his clone.

The clone’s plan to take over the city might stem from the idea: “nobody will bother us, me and my criminal friends can do what we want”. The idea might be a slightly different version of one of the hero's desires, like how "I want to live in peace" and "I want to be known as the best fighter in the city" could turn into "If people fear me, they will leave me alone" and "I'll hurt others to prove to them I'm the best fighter"

The Alligator pit is a good zoo location, as sharks are usually in tanks and it would be more difficult to toss someone in, but you could make it a normal park and have him prepared to drop the father off a small bridge, or into a pond (the man can’t swim very well), or hang him from a high tree branch (the man is afraid of heights), or just throw him as far as he can (bound to hurt), or just prepared to beat him up.
If the father shows fear for the action, it doesn’t matter as much what the action is, really.

I hope that gives you some ideas.

Sandwich stealing is way to serious a crime for a kid friendly comic.

Thank you for responding.

I meant to post this:



HI any writers' here?

I'm a writing a story about streetfighting cats and dogs. The main villain is a clone of the main hero who was created accidentally in the hero's friend's lab.

The clone's plan is to eventually take over the city making it a safehaven for criminals, and to destroy and/or get rid of the heroes.

In a nutshell, the villain vebtures out away from the hero and his friends and is on a trip of self-discovery. He goes to a park and meets an old man who teaches him the value of money. The clone gets hungry and steals a kid's sandwich and eats it. The kid's dad calls him out about it.

I want to have the villain do one of three things:
have the clone guy beat the guy up and over the guy a neighboring bridge (with tons of traffic).

have the clone beat the guy up and get ready to throw the dad out into the main street next to the park.

or the clone starts small, but knocks out the father and threatens to fling him into the duck pond face down, so he will drown.

The clone does one of these three things before the hero shows up to stop him and they fight.

This is a KIDS'/FAMILY comic- no killing or gore.

WHICH of the three ideas above do you like best?

I thought I would go with the idea of having the villain beat the guy up and knock him out and drag or carry him across the street and drop him off a bridge into the path of heavy traffic. He'd be about to drop the guy and the hero shows up and they fight.

Do you like this idea? How can I make this more sinister?

Someone suggested a train station, he threatens to throw him into the path of an oncoming train, a train station is a pretty sinister area, filled with grafitti and low lighting, plus the idea of getting hit by a train is a pretty frightening and sinister thought.

I thought of carrying the guy and getting ready to hold him over a fence populated by angry dogs in a local nearby dog pound/shelter.

What do you think?

I wanted something malicious-it's part of the villain's character.

but it would scar kids for years to come.

HI-could you please help me with the material I posted to oak above?

Personally if you just have the clone get straight to the "I'm gonna throw you off this bridge" It would have more drama with the guy screaming for help.

The clone meets the guy in the park, knocks him out and carries him to the bridge near the park and threatens to drop him off the bridge. So just have him say, "I'm gonna throw you off this bridge" and have the guy scream for help, after he takes him to the bridge?

yeah
