Why is it called being a coward if you beat up someone weaker than you?

I would call such person a scumbag, bully, loser, lowlife, etc. but not really a coward.

To me a coward would really be someone that's really afraid of anyone and doesn't even want to take a chance at all, someone that always likes running away no matter what.

By beating up someone weaker, this person is already showing that they're not cowards at all and can also be just as capable of fighting with someone bigger too if someone tried getting in their way. Yes, I've heard of such individuals who also weren't afraid of getting confronted either.

I actually saw a supposely ''Coward'' one day push the host Steve Wilkos. Sure it wasn't a smart move obviously but at least he didn't care.

To me a bully and scumbag isn't the same as a coward.
