Well look at what they did. There were 2 golden rules in Marvel Comics. No matter what

1. Bucky is dead and he stays dead.

2. Uncle Ben is dead and he stays dead.

And the status of these rules? Buck was brought back as the Winter Soldier and is now Captain America. And Uncle Ben in some form or fashion has come back so many times it is pathetic. No one stays dead in the Marvel Universe. Hell, they even made a joke about it in an issue of X-Men. Wolverine said Jean Grey was dead and Agent Brand sarcastically commented about how long it would last this time.
