Consequentialism is a cute thought experiment, but not more than that since outcomes are always unknown. 

Deontology would be nice, because there would be consistency in the performance of life’s (and the individual’s) moral duties, once they were established. There is a comfort in simply following rules, but history has shown humans aren’t reliably good at doing so.

Virtue Ethics is the best we have but, sad to say, requires a level of thoughtful and empathetic analysis which I think is only interesting to an insignificant minority.
