In the local Catholic newspaper, a priest has written an article saying that Christians must reject the death penalty. And Jesus Christ says to love your enemy. How come the Church tells us to reject the death penalty and the Bible says to love our enemy, but you are in favor or executing some enemies? I don’t see how all of this makes consistent sense.
It just doesn’t make sense to the ordinary person to say that you show your love to your enemy by killing him or by dropping napalm on his children. Perhaps a highly paid New York City lawyer could argue such, but a simple Christian peasant, such as myself, would have a difficult time with such a convoluted discussion.
The example of executing a criminal I cited is just that, an example. You can replace it with any other form of punishment and it doesn’t change the principle, namely that “loving your enemy” is perfectly consistent, at times, with causing him pain and suffering. (FYI, either your priest is wrong or you are misapprehending him. Catholics are not obliged to oppose the death penalty as a matter of moral principle, and the Church has taught that it is licit in principle for centuries).
There is a reason I said that the example of unintended casualties in a war is a very strange one. Normally, when asking how a moral principle applies, you start with the clearest possible case. If the moral principle applies in the clearest possible case, then clearly the moral principle applies in some way to all of them, we just have to adjust to account for the unusual circumstances. Actually, the clearest example would not be the punishment of a criminal (which no one imagines is contrary to love): it would be God, who is love itself, sending people to Hell. God sends people to Hell all the time. If the stories are true, the proportion of people sent to Hell vastly exceeds that admitted to Heaven, perhaps by a 100:1 margin or worse; yet God’s love is unlimited both in scope and in character. He loves everyone perfectly, more than anything. Clearly this doesn’t stop Him from intentionally sending people to eternal, unimaginable torment.
So clearly love itself is not, in principle, incompatible with inflicting even unimaginable tortures on people. Because, again, you cannot love someone without dealing with them as they are, and that includes recognizing that they may well need to die – either because your own life depends on it, or because the lives of those you love depends on it, or because justice demands it.
Where you seem to be caught up is conflating “love” with “niceness,” i.e., not hurting people. That’s a false, modern, understanding of love. It’s not a Biblical or a Christian one. Again, the clearest case-in-point of this is that God, who is love itself, damns lots and lots of people to eternal Hell, yet no one imagines God is not all-loving.
