this isn't going out on a limb to explain anything. it makes perfect sense why an all powerful God will choose to allow evil to enter the world.
Stop for a second and think what your life would be like if every choice you made was determined for you. how happy would you be if you were not able to raise your children the way you wanted, but the way God chose for you? I'm sure you will be the first to say how much you have learned raising your children. Now take all of that knowledge away. learning from mistakes, ours and others is how we grow. it is the purpose of Gods plan. Without it we would forever be like children.
The example of the woman you use is not a good one in my opinion. I have already stated that we have enough people committing suicide over the problems in Israel. If you want to effect change follow the lives of Ghandi and Martin Luther King Jr. These men did not commit suicide for their beliefs, yet effected great change by the way they lived. I find the woman committing suicide under a bulldozer to be a waste.
