I'm a pisces with a scorpio moon and I can't stop being amused at evil things?

I know it sounds really bad, but I used to be so sweet but now I laugh at bad things, like for instance a troll in a section was saying some awful things and I didn't want to laugh but I found it funny, and I was laughing at some advertisement where a women injured herself, i really feel embarrassed saying this to people - but I just want to know if it's a trait from my moon sign?
