Yeah , I hate violence as much I crave justice (something we rarely see in real life). I also think the gang thing was UNNECESSARY and I rather see them fall in love dramatically. But I won't say he didn't reap what he sowed and feel bad for it.
And to see him tasting trauma is actually good because it means his not a psycho and can regenerate himself if he takes the chance.
I know they are running to somewhere quiet, empty... (▰˘◡˘▰)
