captain-flint:

it was entirely selfish and yet entirely selfless of him to choose their fates for them. he saved them and he ruined them. when he said ‘’You may think
what you want of me. I will draw
comfort in the knowledge that you’re alive
to think it’’ i thought i was gonna die. he’s inflicting his own views on them, because as long sa one is safe and alive it’s all good and what has been lost in the process can be easily overcome.

his face when he saw her smile at flint.. he saw the depth of their friendship, yes, but more importantly he came to understand how much they need each other and how far they were willing to go when united. ‘’As long as you
and she stand for it… as long as the
treasure powers it…nothing can stop
it from beginning now.’’ ‘’Nothing but you.’’ 

they were ready to die for this and he couldn’t cope with the idea because he’d have died with them. either literally or figuratively.
