All I remember is that in the synopsis of it the MC is basically a villain or reincarnated as a villain with a system that gives him the option of 2 "evil" tasks and I think in the synopsis the option was like kill 100000 people or steal candy from a baby. If anyone has any idea what this novel is please let me know I've been looking for it without being able to find it.
