Even though Carolina was trying to harm Immanuel, in fact, Immanuel was just trying not to pay too much attention to Carolina. Immanuel just doesn't want his life to really change drastically like what he didn't imagine. Immanuel, he just didn't want Dexter to be in a bad state too, just because Carolina was always bothering him.
In fact, Dexter knew that his wife would do that to the Immanuel family. But indeed they all really can not be reconciled anymore. And that really pissed Dexter off, because it seemed that Carolina had been like that, and he couldn't have made Dexter more patient about it.
Immanuel, and he knew that Carolina was a snake woman, who really couldn't keep what she was supposed to be guarding. And he only made Dexter even more angry, because he knew that Dexter would definitely do something like that. And Carolina also understood that Dexter would definitely do something more cruel, if Carolina had harmed Immanuel.
