Support for wildlife

I was eating my lunch here at a picnic table when I noticed a big red wasp on my sleeve. My first reaction was to shake him off and he then wandered around the picnic table for a while. Then i noticed he is missing a wing. :/

I offered him some okra but he wasn't interested. I offered him a piece of corn, but he looked it over and decided he wasn't interested. I poured some water on the table and he did drink some of that. He seemed most infterested in being near me. I put him on a tree and he crawled all the way back and climbed up the bench I was sitting on. At that point I grabbed some grass, put it in my Tupperware and scooped him into it. Now all he wants to so is get out. But how will he survive with one wing?

Should I let him out? I think wasps eat live bugs so I guess if I kept him, I would have more bugblood on my hands than if I just let him die. It feels cruel to keep him and it feels cruel to release him. What would you do?
