Being a bBounty hHunter

We capitalize the first letter of important words in titles.

After two days of walking over these green lands, I have finally seen someone human.

Running for his life, stumbling over the ground, and pursued by three snapping beasts, a man looked at me from thea distance.

I chosed to help - I don't know why really why, be. Being a bounty hunter doesn't predispose me to any kind of sympathy-.

I've killed all three beasts in three single shots.

The man continued to run without looking behind even without looking to mehim.

Three lives were taken to help one man.

Three to one doesn't really seems like justice; g. Great!

I don't like justice!.

List of verbs/nouns should be similar. i.e. Running, Stumbling, and being. Ran, stumbled, and was pursued. The last item is a little "weird" because it switches from active usage to passive, but it should suffice.

"a man" does not sound right here. I think if you already used "his" earlier in the sentence, you should just follow and use "he." Something also that would be acceptable and perhaps more of what you wanted would be to use "the man."

I chosed to help -I doidn't know really why, beeing a bounty hunter doesn't predispose me to any kind of sympathy-.

Some mistakes, also retain past tense. Don't -> didn't

The man continued to run without looking behind even without looking toat me.

Three to one doesn't really seems like justice; great!
