Viktor is known to be a little bit selfish and quite self-serving. So it's not much of a deviation.
i agree, it seemed like a dick move and really out of character since in the beginning victor made sure not to bite yuuri in case he might've been an omega
While Victor may be a bit selfish, and possibly self-serving, he is definitely a serious sportsman. As such he would never mess with Yuuri's ability to perform or compete as his coach, or even as a fellow athlete.
Enjoyable and fun omegaverse take on YOI for those of us who like that sort of thing. But I have one little quibble, Victor would never have done anything that might mess up Yuuri's performance at a competition. He would have waited with taking those pills till AFTER the competitions were over.
