The saying that one man’s rebel/terrorist is another man’s hero is very appropriate here. There is much to say about the Syrian Revolution but, for brevity, I will address your specific points with my opinion.
Are these men terrorists? 6 months ago I would have agreed with you. It is after intensive study to educate myself on the many facets of the war that I changed my mind. Westerners and fundamental Islamists are radically different groups but, if you can try to understand their world view, there is an inherent morality and logic present.
The choice to fight an armed revolution brought with it the commitment to fight to the end, to death if need be. The withdrawal from East Aleppo was accomplished, I felt, as gracefully as it could have been. There were so many complaints of men (true civilians)disappearing at the transition zones between East/West Aleppo and in the travel corridors that even the UN became involved. Here is a post to get started reading if you are interested. http://www.bbc.com/news/world-middle-east-38260388 With facing the Iranian militias and the high tension, I would have chosen a suicide belt as an option too.
I feel sorry that you think the solution is to kill them. I can understand your repugnance but I do not understand that level of anger. There is a universal Libertarian principle that applies here: live and let live. How do these men threaten you? Why do they deserve your enmity?
As an American, there is a parallel I think about. Our Founding Fathers had to make these choices – to risk all, to give up country and family in order to take the risk to make the country I love. So our ethnocentricity complex that has grown over the years blinds us to other ways of life that are valid for other groups of people. Must everyone be like you to be moral, to have a quality life?
