In the normal course of events you're right but the problem is people like this have proved they're not going to be taken alive and will do their utmost to carry on the killing until they're dead - women, children, young, old it makes no difference to them. In such circumstances, regretfully, the least worst option is helping them on their way as soon as possible. In assessing our response and what results from it, we should remember that every single person they decide to murder is an innocent victim and on the scale of justice, killing multiple murderers is always going to be by far the lesser of the two evils we face.
