Can someone explain the grammar in this sentence "もうこれで終わってもいい"


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.
