I can see how this fucker killed three people
This plan is of course absolutely outrageous, and has an absurd amount of things that can go wrong.
But my biggest issue would be that Maria is perfectly fine with still playing ball after what MC just pulled.
Yes, Maria is certainly portrayed as the type who would do this.
But MC had no way of knowing that. Granted, maybe he has a contingency in case Maria would betray him, so I will withold judgement for now.
