Ramadan, can someone just explain to me, why would Bashar Al Assad gas his own people?

Salam. Because Allah forbids us to kill a Muslim without strong reason(kill other or make destruction) so we among Muslims must respect,love and help each other and we are united. This verse rules not only for children of Israel who did it, but for whole humans we are not not allowed to kill others without strong reason because it means they kill humanism (human as a whole).

By killing someone it means also his descendants.

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.
