People like you are, and I mean this literally, the problem with the world. People who despise those who believe above all else in ethics and morality. People who see ethics and morals as negotiable, and worse, outdated. It will be you and your amoral/anti-moral ilk that end the world in fire.
ethics and morals are always negotiable. a lot of people will tell you murder is wrong.
then comes the 'except':
to save the life of a friend, when attacking a foreign country, when executing a criminal, when aborting an unborn child, when killing (some) animals.
culturally and personally, you'll always get wildly swinging standards on a variety of topics, including sexuality, animal treatment, human interaction, what to eat, what not to eat, what is acceptable behaviour, how to live one's life.
its the moral and ethical absolutists who clash with the conflicting ethics of another group which will 'end the world in fire'.
the other people who realise that their own morals are not universal constants are the peace brokers of the world. they realise that their beliefs are conditioned during their upbringing rather than hardwired in their brain, and are willing to find compromise when they clash with the morals and ethics of others, no matter how abhorrent the other may seem. They recognise that their own personal morality changes over time (its a normal part of growing up).
Conflicting morals between individuals may not be compatible, so we can choose not to live with the other people. We can lock them in prisons so they're away from us, exile them, or just not visit their country if its a cultural thing...
Except for people like you, who'd rather marginalise anybody whose morals don't fit the absolute standard (which, conveniently, matches yours... what a coincidence).
