He still has guilt of killing his brother, with his quote, "Sleep is for the guiltless." He states that his brother was his guidance and mentor.

I mean, he killed his own brother just to defend his honour, he didn't want to die branded a traitor, which is why he ran away from persecution.

Which weighs more, your loved ones lives, or your honour? Clearly Yasuo feels guilty about this.
