The point in this instance, is that the woman cited above appears to be under some delusion that she is performing some kind of spiritual service to the criminal, in putting him to death.

As I said, she could do well by leaving the business of ministering to a criminals spiritual welfare, so someone who (we might suppose) has the relevant training and experience to so so - while the criminal is yet in this world.

Of course the obvious point is that she's glad she put this man down because she believes he deserves it and it suits her desire for vengeful justice. But she can't cope with the conflict that generates with her supposed "spiritual" side (and the direct commandment Thou Shalt Not Kill, if she subscribes to any form of Christianity), so she's constructed a neat get out clause for herself to resolve her cognitive dissonance by telling herself - and the world - that she did it to help him to make peace with God.
