Damon's heart was breaking for Talia. It was her first time seeing something like that, and not just seeing but being in the middle of it. He knew that Talia was drowning in guilt that will plague her for years to come.
He was there about a decade ago when people died around him, for him, and there was nothing he could do about it. People told him it was not his fault, and it was their duty, and that didn't lessen the burden he felt. Actually, it made it worse because he thought of himself as a weak link that was causing everyone near him to die. Those were dark times in Damon's life, and he didn't have time to mourn one death before the next one came, and he wondered if people would be better off without him.
But then he had Caden and Stephanie, and they convinced him that pack without him will suffer, and the only way to prevent unnecessary carnage was for Damon to get stronger. And he did.
