Surety In Strength.

People call themselves civilized but become deaf or unwilling to understand spoken language at certain times. For example, when you ask people to give up their stuff without a fight. Selective deafness occurs which leads to the exhibition of acts of barbaric violence. 

It is fortunate that he is well-versed and very convincing in the acts of barbaric violence. Action speaks louder than words anyway. And a strong gist speaks the loudest. So Selective deafness is not a bad thing for him since he has the strongest fist.

The fight was an efficient use of time for him at the end of the day. He got feats out of it and a lot of high-quality healing pills. There are some other consumables like the explosives but he doesn't care for those. The explosives will be useless in a one-on-one fight with him. He is too fast to be caught off guard by it. He might even be able to kill his enemy before they can bring out the explosive and use it.
