In uncanny avengers #9 they show 4 bodies to whom are given 4 death seeds, but Sentry's body burned in the sun. Is it bad writing or there is an answer to that? To me it seems such an huge mistake that there must be some reason.

Other than that, do you think the void will overcome the death seed and the sentry will go out of control?

There is also a physical mistake (there are lots of them in comics, but it is funny to point out): wolverine heard a sonic boom hundred of miles away, and before he could react sentry made his appearance. Sound's speed is about 300 m/s, so sentry should have come way before wolverine could have noticed anything.

Lol, i had to read two times this comic, things have gotten complicated.

What it is unclear now is if the void cleansing stuff has to be intended as a new mental state or if materially the void is gone. I think that if the void has been able to escape the sun the sentry should have been too, so what really happened is that through endless torture the poor bob got rid of his dichotomy.
