Who's the real monster?

This comic depicts a situation that all too often escalates beyond reason within the community.
It's important to note that some people are more impressionable than others, be it because they're young and haven't found their own identity yet, or perhaps because they experience social disorders that make expressing themselves more difficult. They may find certain characters inspiring and thus might employ some similarities into their own characters.
This is okay.

It's also okay to be concerned if there is a little bit too much resemblance between your character and theirs, to the point where it's genuinely difficult to tell them apart. If that's the case you might decide to address it with the player on civil terms, and if all goes well, come to an agreeable compromise with no harm done. It's not fair to nitpick on details on otherwise unalike character designs, however.

What isn't okay is to treat someone however you like just because you feel convinced that they wronged you. Nor is it okay to backchat to uninvolved people where said person has no chance of defending themselves, effectively isolating and dooming said person from ever being able to redeem themselves, as if you know who they truly are inside, and as if you know what they deserve.

Good intentions don't justify abuse.
Mistakes don't define a growing person.
But you know what does define a person?
How you choose to deal with it.

You.

There is a difference between constructive criticism and bullying. Be merciful to those who've yet to find their place. And bear in mind that sometimes people make mistakes and learn from them.

The real monster isn't a who, but a what. It's mistreatment under the misguided guise of justice.

Disclaimer: This is a situation far more complicated than a comic like this can depict, but hopefully it gets the point I am trying to make across.
More often than not it pays to give people the benefit of the doubt, as most people who take inspiration from others don't do it out of any sort of malice, and are often up for making reasonable changes when fairly addressed.
