HE HAS, BUT THAT WAS IN THE PAST WHEN HE WAS WAY MORE OF A PIECE OF SHIT AND HE DOES TRY TO NOT DO THAT THESE DAYS IF HE HAS TO...though lbr, he will if it's the only way to save someone. Sadly MHA-verse is very much a "Heroes can't kill, but they sure can BEAT YOU WITHIN AN INCH OF YOUR FUCKIN LIFE" type of shounen, so yeaaahhh... He will try to go with non-lethal hits so Sunny will be bruised and achy, but he won't like...have broken bones or whatever. Worst case scenario is he'll be blinded for an hour or two from a flash-bang/stun bomb.

And sob, he probably won't remember Sunny very well, even if they are neighbors. It's canon he is shit with names and faces unless they ping on his radar, but who knows. It depends on how our TDM thread goes pfft (if you wanna continue it).
