IMO, the problem with Buddhism, is it is another "ism", another system of beliefs. Beliefs are inherently restrictive and narrow, which inhibits the unfettered openness of acute investigation into what is truly real, and what is not.
I have found that it's important to loosen and free every stone of our beliefs about "self" and universe. This becomes extra difficult, perhaps impossible if we hang tightly onto any belief, be it of self, god, whatever.
If someone broke into my house, I have no predetermined belief as to response; and so it is highly likely that the natural actions of self-preservation would kick in. Who the hell am I to jdge such natural instincts as evil? This is the problem with religion. It ends up making concrete judgments which divide everything and everyone into groups of good and evil; which sustains duality, and then so conflict and war.
What is it that unites us, one and all? What is it that all beliefs and gods exist within? What is closer than the entire grand drama of things? What is the unmoving foundational truth? These are the questions religion should be guiding their followers to ask. If someone breaks into my temple or house, and the animal instincts of this body flare-up and kill them, so what? It is the nature of phenomena to continually move and change. No natural laws have been broken, nor I doubt, can they ever be. What does not move and change? Other than the "life" story, who/what am I, really? that is the question.
