Well the problem is that she had been treating others too much and since she had been long exposed to the ultra retarded and annoying moeblobtype yukkuris, it's hard to not expect this to sooner or later happen, since we are talking about yukkuris.
There is a limit about how much you can tolerate yukkuris stuff.
The point is temptation against good ones, nobody truly cares about about smacking around annoying ones and people CELEBRATE when shitheads are tortured. So yeah, the point should be to be nice and tolerant to the good yukkuris.
