I like this story. The biggest and very obvious problem is the grammar but I can ignore that since I've read way worse and understood those.

Inane is an actual word though

Those thugs should be hospitalized and still be hospitalized if they actually took damage like a real person

So he should feel guilty for commiting his first two murders

The people who's saying the guy is stupid for leaving the thugs alone are correct, but if you look at how much damage they took realistically the thugs should be crippled and are dying a slow death in an alleyway.
