The second-to-last line is better this way. But the last line was better the other way.
Like, this comic may imply they have lifetime supply of food and houses provided by the anon, or that they'll need to build a house after they die, or that there's some weird reverse-life-insurance going on.
I'd go with something like: "These guys won't get a chance to use these skills [anyways]. Because they won't live [long enough]."
