It seems you have no idea what Thanos is capable of. Not only does it take people far more powerful than Superman to hurt Thanos, like Tyrant, Galactus, Odin etc. Then when you factor in the fact that Thanos tanked a blade that could slice through anything.. TWICE (by Gamora and Corvus Glaive). It takes people far above low heralds such as Superman, Hulk, Nova, Gladiator and high heralds such as Beta Ray Bill, Sentry, Surfer, Thor to hurt him as well. You need to be at least Odin level or more powerful to really hurt him.
That's like saying that Batman overpowers Superman when he wears the Kryptonite ring.
Where does it attribute anything to deaths and ressurections?
Drax is compared to a silver bullet. Silver in general is harmful to wear wolves. The energy surrounding Drax as he approaches Thanos clearly somehow negates Thanos power. The book is all too clear on that. Drax doss not overpower Thanos.
Did you read Annihilation? Have you read anything with Thanos after he was resurrected by Death?
Thanos isn't invulnerable (ok, he is to some degree, much more so than Darkseid and Superman and Thor and Odin and Galactus in recent years).
Drax would be the equivalent of a Kryptonite man. The Kryptonite Man would easily surpass Superman's durability, because it is a weakness of his. Superman can also be killed by people that are physically superior to him. Drax would be to Thanos as the Kryptonite Man would be to Superman.
As for the fight. Odin would godslap Darkseid into oblivion, while Thanos pimpsmacks Odin into oblivion.
And no where in that scan is it even remotely implied that Thanos is weakened by death and resurrection. Straight up made up stuff. Thanos had one resurrection before Annihilation and was stronger. In that scan he is weakened by Drax’s presence.
