He stood up again and again, I thought he was the weakest person I fought but it seems I was weaker.

Salam (Peace)
This is my entry for freewrite day 74, Pormpt Callous (which is a new word for me, not sure if I used it right.)... It was inspired by an answer to a question on the website Quora, so the story is half real.
I didn't follow the rules this time, this story took around 15 minute of me instead of only 5 mins. Editing time is included. But it's still a #freewrite as the edits are minimal.
This is my Second #story-300words Attempt
The initiative by @swissclive is a great one, I advice any aspiring writer to write a short story there. My first story was well liked. It was a children story, this one is a bit darker 159 words.
Too Much Beating
Red.. it's all red.
He stood up again, blood flowing from all over his body.
"Why are you still standing?!" I clenched my fist. "You're already bleeding."
"You callous!!" He threw a punch but I easily dodged it. My beating weakened him. "I'll not let you bully anyone again."
"But you know you're going to lose." I punched his face to the ground. "If you stand up again I'll kill you!"
"I'd rather die! Than to stay up and-- Ugh!!"
"Die then!" I kicked his abdomen making him lose conscious.
I looked to the crowd, then turned away. "Get him to the hospital or something."
I realized I was panting.
He was the weakest person I ever fought, But he gave me the most trouble of them all.
I didn't want to be a killer, I just wanted to have fun by beating him.
I thought he was weak. But he made me realize that the weakest was myself.
[The End?]
What do you think?
I love this story so much I might make a cleaner version of it some day. I wrote it from the bully perspective which is something new from me, though I'm not sure I conveyed it right.
