Stop trying to judge people who chose Chaos
"people are going to choose chaos because they're edgy xd" "people are going to choose chaos because they love evil characters blablabla"
Stop
There are a dozen of reasons people chose chaos, you cannot simply decide what is the reason that drove them into this choise Riot never told us to choose based on a moral reason, we are free to choose whoever we want because of whatever we want
people prefer having soulstealer vayne people prefer the chaos icon Even Malicious told me that he chose chaos because he doesn't like the disproportional body of Riven and i actually share his opinion
it's not "they're edgy and want to look cool" first of all riven is also edgy no matter how you look at it, you would have as many people choosing her as yasuo if it was only for this
And you have to take in account that this is a video game, not a real life situation
i don't know about you, but when i talk with friends in a normal League of Legends conversation i end up quoting
or dunkmaster
i simply chose chaos because when it comes to league the personality of chaotic characters are more present in my mind than characters who would choose order like 
and even then a moral point of view does not give credit to order
Riven wants a peaceful world in harmony Yasuo wants to destroy the world to build an other one
this reminds me of this

Takasugi in gintama he fought for his country against an invasion and they lost the war and was betrayed by his country who surrendered. Then he got hunted for his entire life and he couldn't do anything anymore. The population didn't revolt and let the corrupted government in place while doing nothing which made him choosing the path of chaos to destroy everything And eventually he had to fight gintoki who was his old friend, kind of like yasuo with his brother

Think about it, if you were in yasuo's place you would have been increminated for a crime you didn't do, then forced to exile, then fellow swordman and your brother hunting you and forcing you to kill them which only makes things even worse for you and your country. Are you sure you wouldn't have chosen the same path of chaos?
This "order is morally better" is only a matter of point of view, it seems better for us, but if we were in a situation were everything is against us we would have either the choise of dying, or the choise of fighting everyone and everything i wouldn't judge anyone who would take option 2 i myself do not know what option i would take.
but like i said, point of this thread is we do not choose based on moral.
