[MCU] Why did the Infinity Stones punish Red Skull?

We've seen multiple people holding one or more Infinity Stones. We've seen multiple people trying to assemble them. We've seen multiple people using one or more stones for evil/selfish reasons. But only Red Skull was punished for this. Only he was cursed by the stones. Why? Loki tried to do worse things than Red Skull, and he was holding 2 Stones. Why wasn't he punished? In IW, Thanos wanted to kill half the universe, and in EG he wanted to use the stones to destroy the whole universe. Why didn't the stones punish him for this? Why only Red Skull was punished by the stones?

In a way, Red Skull *wasn't* punished. He grabbed the Tesseract, seeking to use it as a weapon against Cap. He didn't understand its power, so when he activated it looking for a weapon, it opened a gateway and sent him to the most powerful weapon in the universe: one of the other stones.

Presumably he then sat on Voromir for a while, foiled by the fact that the only thing he loved was power & himself. In a way, he made his one punishment.
