darkest thought you've ever had?

curious if anyone has any depraved thoughts they wanna share...

I used to want to see what murder was like, to see if killing changed people. if it would change me. 

During middle school, my manic episodes were really bad, and I used to want to hurt my parents. Not necessarily because of them, rather I had this insane anger that got me into so many screaming matches. 

 I don't think I could ever kill without feeling guilty, though.
