I doubt they will kill Hook. But they may very well place him in situations where his life is in danger, or where the easier choice would be to simply give up.

Go back to the Season 3 Finale, and ignore the final 2 minutes. When Emma gets trapped by the time portal, Hook tries to hold on and pull her out. Then, when she finally slips in, he could easily have just said "To Bloody Hell with it". Instead, he chose to risk his own safety by following Emma into the portal. I think we'll probably see more of these types of situations, from both Hook and Charming. In fact, this situation may be the best way to pull both of these 'Doormats' more into the limelight, and maybe even see a strong bond develop between them.
