Which is what the whole "empathy movement" of recent years seems to emphasize. The problem is that when empathy is unmoored from the objective good, this can become scandalous (not in the sense that it causes outrage, but in the older sense that it encourages evil). Not every response is a valid response. You must be able to identify whether something is good, you must refrain from actively enabling things that are bad, but you must discern whether to correct, and if so, how to correct. Not every problem is yours to correct. Busybodies think they are.

(N.b. the Catholic Church, drawing on ethical distinctions, makes distinctions between moral principle, the objectively moral status of particular acts in light of moral principles, and the pastoral needs of particular persons. So, e.g., while prostitution as a practice is roundly condemned as a matter of principle, particular prostitutes may be treated gently. This is especially true if he/she expresses remorse for the way he/she has lived his/her life (the parable of the prodigal son comes to mind).)
