For my story, there is a gang of criminals, and one of them has a crisis of conscience and wants out. He doesn't go home and hides from home for a few weeks while other plot sections unfold. The gang calls him though and tells him in order to get out that he will have to do something horribly felonious for them so they can have collateral over him. Possibly he may have to kill someone. Later, another character, let's call him the cop since he is one, gets too close to the gang and the gang has to deal with him, before they are busted. They call the gang member who wants out and tell him that if he kills the cop for them, he's out. The gang member rushes their to do so, but it's just a ruse since he has morals now. He is also compelled to save the cop. The cop becomes aware that this gang member is assigned to kill him in order to get out. The gang member gets there and the cop temporarily escapes. In the midst of a gunbattle the gang member is struck by one of the bullets, in the face, and dies. The cop then maims the gang members face even further to the point where he is not recognizable and switches clothes with him. He also takes the gang member's mask and puts it on. The rest of the gang arrives and sees the gang member dead but think it's the cop, since his face is destroyed and he is wearing the cop's clothes. They see that the actual cop is wearing the gang member's mask and clothes, so they think it's the gang member. Since he did his job, they let him go. So far a couple of reader's had no problem with it, but another couple didn't buy that a gang would assign one of their own to kill a cop in order to get out. They just said that logically if they didn't want their gang member to do get out, since it's a risk of not being able to trust him, they would just kill him, instead of offering him an ultimatum. Why wait till someone has to be killed when you can just kill the cop? Basically I figured that one murder is better for two, since it's double the risk of being caught if you do it twice. But what do you think? Is this idea realistic or logical? Thanks for the input .
