So Jasmine told Whistler to send Angel to Buffy so that she may come into being.
Jasmine, of course, was a PTB corrupted by the SP who gave her life in order to corrupt Angel and destroy his support system.
If Angel hadn't been attrracted to Buffy he still would've helped her out of- I guess- finally finding a sense of purpose.
I don't see a smidgen of evidence that he would have helped Buffy herself - but I do think he might have helped whoever Whistler told him to help.
Up until that point he'd had nothing but disgust and betrayal from people and demons of all types. He was neither one thing or the other.
Sorry to burst the myth, but not if you believe Angel:

In all the scenes that they show us, Angel is wearing decent clothes - particularly that tailored suit he wore when he rescued the puppy - in the middle of the depression that cost some real money! He was able to feed himself, and always has some place to live - so he has some source of incomes, contacts to get blood wherever he moves, an ability to find and use stores to get what he needs including luxuries like a radio, and a fan.Even travel had to come with some special challenges, and he did a lot of that!

For 80 years, until the raunchy rat blood period, he had consistent human contacts. He may not have had friends - I assume he didn't - but he wasn't a pariah. Overall, he actually did pretty well for himself. Oh, and I don't think he was depressed in Missoula, or at least I don't think that was what he was actually going to say.
