depends on what you refer to as gamers
if you're referring to "people who play video games" as gamers, than no, playing a video game does not make you evil
and if your talking about the gamers that are play minecraft and fortnite 24/7 than even if they are really annoying, they arent evil.
For someone to be classified as evil, they need to be an actual bad person or support something bad
someone isnt evil for liking video games
