A sin is anything that pushes you away from God. So like

alluded to, that which occurs within you is the deciding factor.
In Doom you're killing demons, so that's a good thing, but if you take that action and turn it into glorifying violence in general then it can have an adverse affect on you morally. I haven't played Doom since in the videos I saw it didn't seem too good, but when I was playing the beginning of "Call of Duty: Black Ops II" when Woods is shown all beat up and lame then when a Black guy got burned alive I felt like I was doing damage to my internal moral compass. Like, if it's okay to do fucked up shit to these people then maybe that shit happening in real life isn't so bad and doesn't warrant objection.
However playing Doom can have a positive effect on you as well. You're taking an active role and standing up against evil. With endless Anime posters on chan sites playing video games can be a way for you to become more masculine and dominant.

>Making stupid threads is a sing.
This poster actually made a good point in that with the idea that anything that pushes you away from God is a sin, endlessly browsing threads can push you away from God in that you become dumber and less averse to a low quality life. God wants us all to be happy and successful, so wasting your youth away without producing anything intelligent or creative contradicts that will.
