Consequences of non-consequentialism are disastrous. Just look at charity - instead of trying to get most good-per-buck people donate because this "make them a better person" or "is the right thing to do" - essentially throwing this all away.

If we got our act together, and did the most basic consequentialist thing of establishing monetary value per death and suffering prevented, the world would immediately become a far less sucky place to live than it is now.

This world is so filled with low hanging fruits we're not taking only because of backwards morality it's not even funny.
