I'm not familiar with the lore of every champion in the league. The question of Shaco's admittance is brought up within his background, so one would assume it wasn't the standard operation of the Institute to allow crazy murderers to join their ranks. Mordekaiser... I don't remember what his original lore was, but I believe it was quite different?

And yes, I did concur that the Institute may just be mad and don't give a fuck about what their champions do in their free time. However, Lissandra simply breaks all reason.
