Moral behavior depends on self-control, but kin altruism does not.

Evidence

Willingness to help others is lower during ego depletion than at other times (DeWall et al. 2008). The only exception is willingness to help kin, and that is unaffected by depletion, which suggests that the impulse to treat kin favorably may have a different and stronger biological root than any impulse to be kind to non-relatives. Although moral judgments seem largely unaffected by ego depletion, moral behavior is highly sensitive to self-regulatory powers. Self-control has been called the “moral muscle” (Baumeister & Exline 1999) because it constitutes the capacity to override selfish impulses and to do what is morally right instead. — Nicolas Baumard, A mutualistic approach to morality, 249
