Who was the most sadistic serial killer of all time?

I can understand why ramirez got married, k mean , have you seen the freaking guy? He's beautiful. Of course that doesn't make up for what he did, but damn he was hot. Lol. I think even though he didn't kill too many people he was oneof the most sadostics I've read about, right after Bundy. Also the killer clown, John gacy. He gives me chills lol. I love serial killers, they're so interesting. By the way, y is ramirez still alive?!
