Is radioactivity a blessing or a cruse?

I think you mean "blessing or a curse"...not cruse. Anyway, it's really a matter of opinion. It is helpful in curing cancer, but then it also has bad side effects.In my opinion: while it has it's uses, I think we would, for the most part, be better off without it.

Most of the time, all it causes is death and destruction and is just another weapon people use to get rid of people they don't like.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
