I'm having problems with the particle で and its main function here. I can't figure out the real meaning of this sentence.
もうこれで終{お}わってもいい
I found that [Verb + Te-form + もいい] is used to ask permission to do the action of the verb, which conflicts with the context of the scene (a firm, decisive affirmation) from this page of a manga:
A bit tricky without more context but, the whole passage seems like:
"And now with this (something), (it doesn't matter if/I don't care if) it all ends now. So I'm gonna give it everything I've got..."
The first bit もうこれで is pretty ambiguous.
Literally translated:
もうこれで - So with this...
終わってもいい - It's fine if this is the end.
だから - So...
ありったけを - Everything I've got...
It would be helpful if we could see the surrounding pages as well.
Edit: Fixed a misreading with updated meaning.
The line sounds like, “It doesn’t matter even if I end (or die? if I correctly understand the context) now.”
ても sounds like “even if”.
