Or as he said he knows Thor will be his end but he didn't know when so you can't really insult Galactus either way. It doesn't appear that he can see literally word for word event for event into the future.
I can understand that, but from a narrative point of view, it still makes no sense. Why boost the being you believe to be your end? Why bestow him more power when he’s not under your full control?
The Surfer is a prime example. How many times has the Surfer betrayed Galactus? Yet he never takes the power back for some reason.
Story wise, Galactus should have imprison Thor so he could delay/stop his demise. This open the flood gate by having the writer bringing Thor’s Asgardians allies into finding away to free him.
