Look deeper into why or for that matter one finds it personally offensive.
As I've said a couple of times now... I don't find things offensive. So why do you keep asking me this question? As to why other people find things offensive... there's a natural evolutionary tendency to conform to the standard of one's particular group. As an example, some people find it morally reprehensible to purposely harm a dog, others think that it's perfectly acceptable to shoot them, and still others think that they're delicious.
So if you think that morality has a single divine source, then that source certainly has some issues to work out.
But even if one does not adhere to civil Law, their conscience and guilt tell them that it's bad.
Except that my conscience does no such thing. The law is just a human construct. I can understand how some things can be socially beneficial. But from a God's eye view, they're only immoral because we say that they're immoral. Morality is just the evolutionary forerunner of laws. The building blocks of society. No divine authority required. Unless you consider evolution to be God... which wouldn't be an unreasonable assumption... it has all the attributes of God.
You say you love your neighbor, why? What compels you to love your neighbor, in other words where does this originate in your faculties?
I love my neighbor, because hating my neighbor is irrational, stressful, demanding, and offers no personal benefits other than a perceived social acceptance. So, not being concerned with social acceptance, why would I choose to do it?
It's much easier to simply accept my neighbor for what they are, and do unto them what I would have them do unto me. A simple law... without all the sanctimony of morals.
Oddly enough, perhaps I simply love my neighbor because I'm too darn lazy to hate them. A bar that most people find remarkably easy to clear.
But creation has fallen due to sin. This lion eating a gazelle wasn't like this in the Garden. They lived in harmony and death was no where to be found. And this fallen world is going to be restored as it was in the garden through One Man's Act of obedience. He paid the ultimate price with his blood to undo what has been done by another; namely Adam.
Myths and legends can be wonderful things. In this case the tale of the Garden is a rather simple metaphor for man's naivete... and the loss thereof. Evil entered the world when humanity lost its ignorance and with it, its innocence. Humanity recognized the consequences of its own actions. And in recognizing them it categorized them as good and evil... and morality was born.
Unfortunately, the knowledge of good and evil leads to the knowledge of injustice, and humanity ends up fighting against a foe that it's ill equipped to defeat, because it's self perpetuating. One person's just actions, are another person's unjust actions, and the cycle never ends.
Unless you're like me, and you simply choose to end it. Take vengeance to the cross, and leave it there. You won't suddenly go back to the innocence of not seeing the evil, but if you can accept it, like you can accept that lion on the African plains, then you can replace that lost innocence with wisdom... that life is, what life is.
For example: is the following evil acts, The Holocaust, Mass Shootings, Raping children, Murdering Children, 911, Wars where many lives are lost, terrorist attacks and so forth. So, for me to accept that's not evil and it's one person's personal delusion is absurd for me.
To you these things are evil, probably deserving of retribution. To me they're just lions on the African plains... life being life.
My suggestion... stop and think about that lion. If you want him to stop killing gazelles, then don't punish him, make it so that he doesn't have to. People do evil things for a reason, your goal is to remove that reason. And the first step is for you to recognize that your vengeance and retribution is part of the problem.
