That's understandable and with philosophy it's good to have different POVs to gain a better grasp of ideas. Have to say personally without philosophy i'm not sure if morals/ethics would exist since people wouldn't delve into the deeper side of things.
Philosophy will exist as long as humans exist. Everyone of us encountered a philosophical problem in his/her life.
To an extent I agree. I still think that if you have to sacrifice ten people to save a thousand, you have to save a thousand.
Life is never that one-sided. Edit: Even in wars.
How negative a view of the world everyone has.
People and society are still evolving and improving in small and large steps and jumps. How would you feel about the world if you happened to be a non white non male living in the 1930s. When is the last time that half the population of your town died of the plague?
People have come a long way in the evolution of morality, just look at what people in the old testament thought was a moral choice ( all that killing the first born babies of Egypt and the whole lots daughters thing).
It is all of our jobs to make the world a better place for all future generations and not just ourselves.
I actually think the "evolution of morality" nearly reached its peak. I don't mean that it will stop eventually/ever (if we just consider that some societies might fall back or that always new philosophical problem rises like genetics), but the problem with moral and that stuff is that people still need to adapt or at least think about it.
