Review Detail of _EMI_ in Marvel: Meditation System

The only motivation that MC has is that he's trying to survive because Thanos is coming, yet in my understanding, these conditions with his Nen abilities are like risks. However, even if Thanos do the snap, there's about 50% chance of survival, so isn't it a bit too much with this whole "desperation" thing? I mean, I feel like this is overplaying it because MC doesn't seem like someone who's paranoid enough to go this far to prevent something where he only has a 50% chance of death. He's shown enough bravery, he's fought the Avengers even when he wasn't sure of winning, he's messed up with SHIELD agent even when it was way more riskier, so what's with this whole "desperation" thing, and "neutralizing threats"? Isn't that just hypocrisy? Because who can be more "threatening" than MC? Let's not forget, it's because of him that Ancient One can't see the future, yet she chose to help him instead of eliminating him? It makes no sense whatsoever.
