I suspect the Snarly One would be undemonstrative, but would besides protecting the child, take a great deal of interest in preparing baby for life. In fact, that would be one reason he wouldn't be very affectionate-- he sees the world as cold and wants junior to be ready for the feelings of rejection etc that come in life. (Never mind that a sense of unconditional love is more likely to work as a buffer. A psychologist Avon isn't.) He would however, teach the kid life skills-- computers and such, of course, but even younger, he might play hide and seek with junior on the grounds that "The child needs to know how to hide on board ship the next time we are assaulted." In short, um, he'd be a lot like my dad. This is probably why I don't plan to have kids. I take after my father.
