this is where the mythological concept of sin sorta helps. So its a bad thing but basically you decide at what point doing the bad thing is worse than other bad things but you can't ever make it not a bad thing. You just accept its price at some point and its ultimately and individual decision and I don't think many will know until that moment. For myself I try to avoid it as much as I can but I don't know in what situation I will be driven to it.
