The ending to Gears of War 3 left me a bit confused. After beating the game, you find out that:
... Adam Fenix injected himself with the emulsion to accelerate the transition into a lambent human. He then tests his weapon on himself to see if it kills the emulsion (which was determined to be a parasite). In the cut-scene at the end of the game the weapon actually kills Adam Fenix, he said he is too far into the transition to be cured. This is where the confusion lies. When he tested the weapon on himself, shouldn't it have killed him then, rather than at the end game cut-scene? Surely when he tested the weapon on himself it should of cured him and then consequently not kill him in the final cut-scene.
