Thanos can't win, because if he did, then he'd destroy the earth, and then there'd be no Phase Four.

Unless he kills the Avengers and Guardians and takes over the world, then the new heroes come in like the Rebellion in Star Wars

Also I don't think they'd give Thanos the exact same death scene as Ronan. I can imagine the Infinity Gauntlet would have a more spectacular effect if that's even possible, possibly rainbowfied or else pure white light, but Thanos probably still survives either way, unless they really do go for the Supernatural approach (but Lucifer didn't even die in Season 5)
