I don't get their logic at all. Don't you want to do anything you can if you want to win? Wishing cancer to a healer, how exactly does that help with your goal? Trashtalking your own teammates before the match even starts and setting a bad mood, how exactly that will help you to increase win rate?

These are people with total moral degradation, the lowest of the low, they don't deserve any wins or rewards. And people defending this behaviour only result in driving away new players with remaining 'elites' and their 15 alts swimming in their own toxic piss.

The Feast is RNG, you may win or lose, deal with it, accept it, or don't que at all. Being a civilized human being and not being an asshole will always overweight any win ratio for me.
