We are all, always responsible for our actions. Were not responsible for our thoughts or feelings only what we do with them. :-)
MOST people that are abuse don't become abusers...but that doesn't mean they haven't carried and maybe still carry the scars from that abuse
Most people do not inflict that same pain on others...and I think that there are lots of those non abusive people who still struggle with the pain of their abuse
some can get past it all others can not
It could be but you know it is more complicated than that. I know people who have suffered abuse but did not do anything bad or unusal. they became great citizens. Move forward/
You don't know what someone else goes through or went through; it's not your place to judge; and nobody is giving excuses; it's known that anything traumatic that one goes through, can affect them greatly; you're right; not all abused people turn around and abuse others, but it happens, and that's why it's important to recognize it and stop the cycle.
