Oh no, she'd be angry, and possibly messed up, too.  If she didn't love you, though, then she wouldn't care.  Compare your reaction to the story to what would happen if you were the ax-swinging-slasher and told your mom.  See my point?  That's why parents get so angry, upset, etc., when bad stuff happens to their kids it hurts them on the inside.
