All he wanted to do was kill this man to get rid of the last thing that linked him to this event. He knew that he couldn't get Ryder now without getting himself in trouble. Since Ryder had such a high reach, there was a chance that he could get federal agents to investigate, which would've put him in trouble.
If the Federal officials came to investigate and talked to this man, then there was a good chance that the truth would be out, which was not beneficial to him.
"Stop! I promise I won't tell anyone!"
"I'll take all the blame on me! Don't kill me!"
The man kept screaming, but all he did was get even more beating.
"It's better that you die after all. Case closed. There's nothing else I can do now anyway without getting myself in trouble as long as you're alive!"
He kept getting beating until the man was dead.
