Why would he he have something against hunters that specifically gather berries as well?

If doesn't mean he is it means if.

"they took to much pleasure in the "kill""

I get something of an adrenaline rush, I'm sure that's pretty common. Not pleasure though.

The word I believe he should use is poacher not hunter, sport wasn't mentioned in the 2nd and 3rd lines.

Why does only hunting out of necessity mean anything, it doesn't matter if you need to or like to. As long as you just don't kill and not use its fine with me.
