First of all, you have to have watched the movies to understand the Thanos snap
Basically he believes there are too many ppl now, overpopulation, as well as people being unappreciative in general
So his quest is to attain a collection of infinity Stones, which would give him the ability to 'snap' away half of the population
Let's be honest, the guy was right lol, the world is overpopulated and of course it will continue get worse & worse until there are short she's in everything
But of course, everyone believes his way of going about 'correcting' things, is murder
If I were given the choice that half of the population could be snapped away, and I take my chances 50-50 of whether I'd be spared or snapped away, I think I'd take it and roll the dice
If I'm one of the half snapped away, oh well, the other half will benefit
It that mental lol?
