maybe our concepts of personal responsibilty vary rather alot.

for me it is how my actions or lack of impact on myself and others.

i cannot and will not take responsibilty for what others might or might not do.

for example, it was my fault i crashed the car even though the wrong road surface was used, because of a lack of training of what to do on a slippery surface. i did the right things, but too much, i oversteered and over accelerated to get out of the slide.
what i don't do is blame the person driving the car i hit for being in the wrong place at the wrong time.

however if that person had got out and slapped me, that would have been their responsibilty.
