Ever since Yuri betrayed Makarov, he's been happier. However, there was still that underlying guilt that was felt—the two were close friends, how could he not feel guilty?

"I hate Vladimir," Yuri hisses, his voice filled with venom, "he changed too much for the worse."

Though he spat those words out, there was still a hint of guilt in his tone. He didn't want to say these things about Makarov, but he knew he was right.

Makarov, surely, was also his friend. His ally. His betrayer.
