We all fuc**** understand you, Sasha,! But Julian was absolutely right. Im going to repeat what I said in chapters before:
You can't do whatever you want.
And because of that, Sasha dug his own grave when he decided to abandon Karel. Sasha knew well this would end Karel, that it would make him feel wounded. And that's why he did it. I didn't tear up, but it's literal shame to do that when you know exactly what's going to happen and when you know all his sacrifices. It's dissapointing, I can't say less than that.
