Guys watch this show called 'Dexter'. Great 10/10 show, I recommend it over everything. It has 8 seasons, I've watched all of them a year ago and I'm already rewatching it & on season 2. It's about this sociopath dude who doesnt feel love or any emotions and shit, he works as a forensic blood-spatter guy at this place with a shit ton of detectives. He's a serial killer and nobody knows about it and it's super cool. Go watch it.
