How would an unarmed fight between Harry and Kim go?

Me and my friend got done playing this game together and now we’re powerscaling Harry and Kim. Both are obviously very capable men who can easily hold their own, but I want to hear your thoughts on how a bare hands, no weapons/armor fight would go down.

Harry’s advantage is that he’s quite big and seemingly strong (he lifts that weight in the gym no problem even in his…state), but his disadvantage is that he sometimes does things without thinking and has incurred major physical damage from years of alcohol and drug abuse.

Kim’s advantage is that he’s wiry (better for dodging), thinks things through, and has good focus and self control. His disadvantage is that he has a small stature, less musculature, and bad eyesight.

What do you guys think? Who would win, and how badly would the other be defeated?
