[MCU] Endgame Spoilers

How was Thanos planning to destroy then create another universe?

Thanos got *maimed* just snapping away half of all life. Wouldn't destroying the entire universe alone kill him, nevermind creating another?

That Thanos had never held the Infinity Stones. He didn't know the toll it would take. He just knew that, in that timeline, he'd succeeded, but people had travelled through time to erase his perfect vision. So he'd need to... adjust things, a little. 

It is entirely possible it would have killed him. Or maybe not. Maybe it would have killed him, and also everything else. No restart - just death. Maybe destroying all life would cripple him, and he would be left alone in a universe without the strength to create new life. Maybe he could do exactly as he planned, but he couldn't survive it. Or maybe he would just have to give up *two* arms, but his vision for the universe would be fulfilled. 

It's hard to say. 

In any case, Thanos himself didn't know either. He may not even have known using the gauntlet would hurt him at all. So he was *planning* to snap his fingers and create his new, 'perfect' reality. 

What would have actually *happened*... is anyone's guess.
