There is a scene in the movie where
Scarlet Witch was, what looked like, tearing Thanos apart as his armour cracked, in the final massive battle scene. Then Thanos called for his ship to fire on the ground to get him out of the situation. Did Thanos really need the help, as in was he not able to get out of it? It looked like he was dying. I didn't think Scarlet Witch was that powerful.
