Why did Christ die? For the forgiveness of unethical misdeeds and failings. Take porn for example. Porn is rather unethical and shameful in so far as it's use can be as a tool of fornication. Lust is one of those things we need to cleanse away in an ethical sense when we see hope before us of a permanent place in the Kingdom of God which does give us reason to try and stay free of it. Lying is addressed as a more primary ethical failing though by Jesus (John 8). Murder too which includes murderous tendencies which love the idea of someone dying, perhaps when angry or jealous regarding them (as the new disciples mentioned in John 8 were with Jesus). It is the teaching Jesus gave that looks beyond the unethical action to the underlying condition that leads to it, such as hatred or dishonesty or lustfulness, so behind the use of the porn Jesus would call out the lustful inner state of a person. I confess lustfulness at times among other unethical tendencies. It is all part of being human which means being basically unethical by nature. This is why Christ died for the forgiveness of it.
