I think you hit it with the last couple of sentences. He'll probably keep the weapons to himself if Ezekiel continues to refuse getting involved. And yes when he dies which I think may be soon, Daryl will take someone from the group to get those weapons.

 

A long shot.. I think small chance he may deliberately provoke Saviors (push them hard at an exchange) to sacrifice himself to prod Ezekiel. The reason I am considering this possibility is that Darryl told Richard he should give his own life ( I forget exact words).

 

I liked Richard until he pulled this crap with Carol. He's desperate to get the Kingdom in the fight.

 

There was definitely some heavy foreshadowing in that scene. Richard said he'd die for the Kingdom and Daryl responded with something like "why don't you then."

Richard is a good character but it's pretty clear now we're going to lose him before the end of the season.
