One cannot prescribe to anyone whether he should follow an ethic of absolute ends or an ethic of responsibility.
Non-violence leads to the highest ethics, which is the goal of all evolution. Until we stop harming all other living beings, we are still savages.
In law a man is guilty when he violates the rights of others. In ethics he is guilty if he only thinks of doing so.
An ethic of ultimate ends and an ethic of responsibility are not absolute contrasts but rather supplements, which only in unison constitute a genuine man — a man who can have the ‘calling for politics.’[Gesinnungsethik und Verantwortungsethik nicht absolute Gegensätze, sondern Ergänzungen, die zusammen erst den echten Menschen ausmachen, den, der den »Beruf zur Politik« haben kann.]
