Brady’s Monstrous Actions

Where’s the remorse coming from Brady?, yes, I know how he feels about Kristen, given that he had brought up that he wants that female dog out of his life, with what he had brought up to Eric, but he sees what this is doing to Kristen, I can’t see him relishing in how Kristen is reacting like this, given, that he’s enjoying this, especially, given that Kristen was there once before, when Victor & Xander had given Kristen, Sarah’s dead child. Then I have read that someway, somehow that Kristen overhears between Brady & Eric they both had a hand this, why aren’t they playing that up?
