Why does Sakura always hits one time?

[ClarifyingThings]

1 punch already does so much damage, if she lands more hits she will decimate the opponent, Shin was knocked out on the ground, finishing him off like that seems cruel.

I can give sakura some credit this time, at least the enemy got damaged, but usually her attack does bare minimum damage and usually it's only one punch, I just think it doesn't make sense, why she never has a full fight, only maybe in this case, it's acceptable sense the enemy was basically defeated

No Shin's dad was the one who stabbed him with that knife on purpose. It wasn't an accident. Just look at his eye before the knife gets thrown. He needed an organ donor.

Father looks surprised, "ugh...."

Onions are down, they can't use their eyes anymore apparently

His ugh was probably just the grunt when you're trying to do something. It's more obvious here when they actually talk about Sakura taking out Shin's organ.
