Well, had the thing with Ryu not happened, I would have assumed that. But then again, he only didn't kill Gen because Gen wasn't a challenge before. He knows Gen wants to go out guns ablazin', and who better to grant that than Akuma? Gen bugged Akuma a bunch of times but because Akuma only seeks to have a better fight and isn't interested in helping anyone, he told him to piss off.
But now, he kills Gen so that dude can have peace. It's not like Gen was just waiting for the bus and Akuma comes around the corner and lights him up. The old dude simply wanted to die and Akuma granted that request. Gen comments on him becoming a beast, and Akuma questions this and yadda yadda.
Cut to him fighting Ryu. Now, at that point, he should have killed Ryu, especially if he's turning into this beastly asshole. But he doesn't. In fact, they have a chat and Akuma is like "come find me when you figure out your path". If Akuma was out to murder fools that fight him now, why didn't he neck Ryu? Because the dude still wants a good fight, and deep down, Akuma is still human. That was sorta the point of the story, is that Akuma can't really sever the bonds of humanity, or at least as easy as he thinks.
You just salty cause your girl got hit.
But you aren't wrong.
Then again, I honestly think the biggest issue lies with the AR stuff over anything else.
That's why I hope and pray that Capcom doesn't listen to the community. They'll take away the fun parts because adapting is painful and takes work. Urien needs a few nerfs, but not enough that it removes the fun outta his character. So either they nerf him a little but down to a better level and people complain, or they nerf him a lot and people complain that the fun is gone.
No winning.
