People in different cultures think very differently about abortion. Abortion is not seen as a moral problem for example in Sweden or Russia, but it is seen as a difficult moral problem in China and in the USA.

Even where people in different cultures agree they may all have gone wrong.

How could it be that I had a legal obligation to kill people I did not know, and who did certainly not consent to it, while my father's doctor could not help my father to die when my farther asked for it? My consternation brought me to moral philosophy and a life-long search for an answer to the question when and why we should, and when we shouldn't, kill.

If two norms conflict, if they are mutually inconsistent, then at least one of them must be false.

Normative ethics, pursued as a free, systematic, and critical attempt to find moral truth, regardless of religious and other authorities, is a rather new adventure. Let's wait and see what will happen!

The US two party system is very different, of course. Here the people decides about who should rule them, but it is not reasonable to claim that the people rules itself through the political institutions. In comparison, I find that the standard European system is better, also as a model for global democracy.

We own ourselves. This is the core of a libertarian theory of rights. But on this theory, while we are at liberty to kill ourselves (regardless of the consequences of others), we are not allowed to kill others, not even if this means that there we be fewer murders in the future, totally speaking.
