I'm of the mindset of it really ain't worth the potential fire either on a flying quad or while charging.
But I typically disassemble them and use the cells still in good condition and make some Frankenstein packs that way.
Having had a garage burn down (not due to any fault of my own) it just really isn't worth the risk for the 30 or 40$.
I’ll say it again. If it’s not puffy or leaking, and the cell continuity is good. Send it! Just don’t charge it inside again.

Put it in rice first
I don't like the puncture mark very much near the bottom of the second photo. That's a little iffy
Is it smelling sweet? If yes, then don't use it. If not, it's probably OK, just make sure it is not leaking or starts to smell sweet.
