So, aggressor(guy #1) starts fight, soon finds out that he isn't as good of a fighter of the other person(guy #2), starts losing fights, panics because he(guy #1) may actually get badly hurt in the fight he(guy #1) started, shoots other guy(guy #2) for winning the fight, claims self defense because guy #2 was super good at defending himself and could have really hurt Guy #1.
How does SYG account for this? It basically punishes the victim for defending themselves if the originating aggressor is an armed dummy that sucks at traditional fighting.
If the SYG laws stay, they need to have changes to account for this.
Using your hypo, if aggressor (Guy 1) starts the fight, he has no right to SYG. According to KSA 21-5226(c)(1), he has no right to self defense, period, unless (a) he has reasonable grounds to believe that he is in imminent danger of death or great bodily harm,
and (b)
he "has exhausted every reasonable means to escape such danger other than the use of deadly force."
So, again, SYG just doesn't come into play in your hypothetical.
