It comes off as a little macabre to exploit the man's murder just after he dies by recreating the weapon for profit.

I disagree. He had mostly positive things to say about Abe, he' a gun channel, and that gun was in the news. I would have done the exact same thing in his position; it's an interesting question to see just how easy or hard it is to create that exact style of gun. It was more about the gun than the death itself.

But, if it makes you feel any better, YT throwing a hissy fit and suspending him probably cost him $20k in missed revenue, so he certainly didn't profit. As he said, he created the most expensive pipe gun in history.
