QUESTION: Anarchist Ethical Writings

I have been trying to find ethical writings from an anarchist viewpoint. I briefly looked through Kropotkin's ethics and found most of its arguments to be based on anecdotal evidence and personal reflections. I would like to find something more rigorous and substantial in its argumentation and evidence. Of particular interest to me are discussions on asserting oneself without imposing upon others.

On a sidenote: in issue 2 of crimethinc's Rolling Thunder there was an article titled "cycles of abuse and survival" about the perpetuation of abusive relationships between people. If you are aware of anything which furthers the inquiries and arguments put forth there, mainly how and why people perpetuate abusive relationships amongst one another, please let me know.
