Intuition and uncertainty

A. You constantly attack those who matter and act out of emotion, but on the other hand, you yourself sometimes say that you decide things out of your personal intuition, which in the end is also something that is based on a certain emotion and not a certain intellect (but perhaps you understand the concept of intuition differently, I would appreciate it if you could expand on that)?
And furthermore, surely emotion is important for morality, such as compassion, charity, giving to others, etc., which a person does not do except out of having a certain emotion toward the other?
B. If nothing in the world is certain, then why do you waste your life on your religious commitment and make claims with such decisiveness and certainty?
