@Dead_Doll I read the novel and I can most importantly say from my own interpretation if you don't mind that.
aelock was always the subject of love and the only one in klopp's heart, obviously in a toxic way, but he was an alpha he was an Aristocrat and he was arrogant, and "fake" in klopp's opinion. 
Raphael while not loved by klopp, I'm assuming he was clearly respected and is the most suitable pair and he was carrying his child, from klopp's pov. So while he didn't like him the way he liked aelock he still in denial and not only that but some type of like is bound to happen between the two since they are technically married and he's carrying "his child", he ofc believed aelock stole that from him. 
In both lives though, we can see that klopp is obsessed with aelock no matter the way if it's a bad like the first life or slightly more positive like the second. 
So if you ask me even if aelock absolutely had his sin, klopp has a thousand more. And as time grew, klopp was no longer taking revenge for Raphael, but he was living in a he** he created himself by not being able to be with the one he loved and torturing him for that.
