I'm inclined to offer help. Exaltations aren't for people who stay quiet and just try to survive, they're meant to be used - and beyond that, there's no way Molly, daughter of Michael Carpenter, isn't going to jump on a chance to fight evil.
Also, hey, good to know we have literal divine backing! Uriel doesn't seem to be totally freaking out about what we've become, and that's genuinely encouraging.
As for how to word it... I don't think it was ever about us having qualms about fighting the Red Court per se, and that fight hardly showed us the worst of what they do in any case. The main point was the Outsiders, and that's what I think we should emphasise. So:
[X] Offer to help in the Council's war. You managed to kill one of those things, and apparently that's a big deal... and it wasn't particularly difficult for you. All you're saying is - you want to help, and you think the Council needs that help, at least when it comes to fighting whatever those were.
Just the right amount of teenage arrogance there, I think.
