So I've got a stranded kerbal in sun orbit with no fuel or resources except for the EVA jetpack. I'm playing Demo, so there is absolutely no hope of me bringing him home in a rescue mission (docking parts not availble). I have honestly no idea how I ended up stuck in sun orbit anyways (a failed moon landing attempt).
I think the most humane thing to do in this situation would be to end the little green guy's life quickly so he doesn't have to spend infinite years alone and stuck in a capsule. How can I kill this Kerbal in my current situation?
PS: Preferably a humane way that does it quick, but I won't be too picky so if it isn't I don't mind.
