Light 'em up!

Bloody cray cray.

Yes, but they honestly believe that’s the right thing to do. Or at least they’ve convinced themselves that it’s excusable. They believe they have a right to do things for themselves at the expense of others. That’s why they won’t ever have remorse. It takes more intelligence to empathize with others; they don’t have that. It’s actually kinda sad.
People who wig out and do what they know is evil are very distraught, and often suicidal.
