Interesting discussion going on here. People have a tendency to want to see things in either black or white. In reality life is many different shades of gray and perspective is everything.
It sounds like your friend is in crisis and is running - hard. The morality of it is subject to each individual and is most likely colored by their/our own life experiences. IMO i don't think its a bad thing to be a friend to someone if they are looking for help. As long as boundaries around your own life and situation are established.
