The is nothing evil about revealing concealed facts, what's evil is precisely conceiling those facts so as to deceive curators and profit from the resulting deception.

"For everything hidden is meant to be revealed, and everything concealed is meant to be brought to light."
Mark 4:22

My intention was never to hide it, you do not understand, I did not know, I did not know the rules, leave me in peace

You might not have known the rules, but you certainly did know that you were copying other artists work and chose not to mention it, knowing that your failure to mention it would result in curators assuming it was your original drawing , and that is what matters.
Additionally:
Ignorantia juris non excusat.

It is precisely when all the truth is revealed that you will be able to be in peace. And for that, we have a way to go.
