reasonable risk is fine but not "die by the cause". I think the person that says "yes", they have not been in any dangerous situation and think they are in a hollywoodian film where there is always the happy ending or, maybe, are they with suicidal tendencies?.
I risked lightly my life one day. It was early and I saw a cat (I imagine it was a wild domestic cat), trying to cross the street but he looked a little stressed by the cars crossing. I could say there were some seconds of communication between both of us. I saw him, he saw me, I cross the road and I stay with my bike in the middle to stop any car coming and I told him of crossing. The cat understood wonderfully and crossed the street
.
I will never stay in the middle of poachers, they only kill you and put you on the side of the way and that is. It is better to live for the cause and not to die for it.
