Should christians love the wicked?

"Let me insert a question here. Which do you think is a true manifestation of brotherly love? To save murderers, rapists and child seducers alive, so they can wreak havoc on our neighbours and our neighbours' children, or would we be showing more genuine Christian love towards our neighbours if we put murderers, rapists and child seducers to death and saved our neighbours from them? To say we love our neighbours, and then to transfer that love to those who destroy our neighbours is not Christian love. It is insanity."
