Certainly.

Or perhaps the grief has just caused him to regress to the (religious) security blanket of his youth.

Nowhere do I validate or refute his choice to turn to God. I merely state it as an example, without judgment.

Would he cry out to God if he had not been raised religious?

Depends upon the individual. Examples exist of people finding spirituality for the first time in a situation such as this, although more often than not I imagine they've have had some prior exposure.

Again there are options other than logic, science or spirituality. How about his own gut feelings on the matter?

Of course. While "gut feelings" is an imprecise term, most probably referring to intuition, which could be based on a number of things (including the things we've already discussed), your point is well taken, and I agree. I always have, in fact.

Any system that relies on external input to tell a person the difference between 'right' and 'wrong' is flawed. That knowledge needs to be intrinsic to an individual, not extrinsic.

All systems are flawed -- this I promise you. And it could be argued that all knowledge comes from outside the individual -- even logic, which is based upon learning of one form or another.
