Now I feel worse for reading it, hr could have done so many other things to protest instead of this, poor guy, may he rest in peace.
I strongly agree with you. Though, self-immolation is a from of extreme protest which have had a long registered history of taking place since the beginnings of civilisations, which leads me to believe he knew what exactly was doing and he did not simply wanted to be part of a pro-palestine march (like the many which have taken place around the world). He wanted to become viral, become an imagine of protest around the world, and he managed to accomplish his objective (at least for some time, a couple of days).
Honestly, I would have preferred he did not sacrificed himself this way and reached to get the mental help and counseling from a professional or his family. He was even trying to get out the army and learn how to become a profesional engineer... What a waste of dreams and talent.
Also, I was not expecting him to survive after I watched the first seconds of the video. Usually, the people who commit self-immolation know that surviving usually means a painful existence with their body completely covered with crippling burns, not even mention the disfiguration, so they make sure to use enough fuel for them not to be saved once they ignite the fire...
