I absolutely would, where it's legal. Many Catholic churches (to take one example) share property with a grade or high school, so toting in those churches is verboten. As to my emotional state, I can't imagine any level of bereavement that would impair my ability to use a weapon in defense of self or others.
As to carrying in houses of worship, heck, even our state AG issued a formal opinion saying doing so was perfectly fine. I wear a suit or jacket and tie to any funeral, so no one is going to know I'm armed. I've also perfected the "CCW hug," to get my right arm in low, first, forcing the other person to wrap my upper arm, rather than the butt of my pistol.
