Do you have a villain OC whose tragic backstory EXPLAINS their Evil, but doesn’t JUSTIFY it?

The Gentleman (real name Charles Barley) was once a little kid who was experimented on and abused by his scientist parents, and was bullied in school, due to seeing kids in pain and suffering around the world, he started a Child Revolution, and his grand plan is to make a world with only children by planning a total adult genocide.

The Gentleman’s whole point is to make a villain who you’re supposed to sympathize with, but not excuse their vile actions one bit.
