It seems to me that altruism is evolved, hard wired, rather than learned from influences. Watch kitten siblings fighting and stalking each other. They are practicing their skills, but they never hurt each other badly. How could humans live in such a huge, complex society of strangers without altruism? Guilt, shame, pleasure in helping another, all hard wired to an extent. They can be nurtured, or alternatively knocked out of someone by a chaotic upbringing.
