comparing negative Betas

Hello, I have another question regarding negative betas:

For my mediated model, if the B from the first regression (predictor->outcome) was, let's say -0.55, and the B of predictor->outcome on the third regression was -0.02. Would I still treat this as a situation where the B from the first regression is "greater" than the B from the third? Since mathematically, -0.55 is a smaller value than -0.02, but in terms of relationships, -0.55 still represents a greater amount of change per unit of X?

woops, sorry for the double question.

No problem. It was just a kind of long explanation, so chances of saying it well twice were not all that good!
