Loki is primarily a Jotunheim Frost Giant (albeit a smaller version) as such he has expanded life span, super strength, insane resistance to cold, and has taught himself magic spells. Loki considers himself the God of Mischief but he's just an alien being with powers like a Kryptonian (although not nearly as powerful) and can be killed if a sufficient enough force is used.
He tends to come back, MCU kind of dropped the ball by nor having him self resurrect as a small child or animal or something.
Heck he pranked Baldur by letting him think he sold out the realm, letting him lop his head clean off, and as he rode away in a murderous rage had his headless body walk to his noggin, reattach it, and laugh about how a stiff neck is totally worth the joke, while self patting himself on the back about how any mage worth his salt can survive a beheading.
Surviving is what Loki does, even when he doesn't.
