Hmm. As a muslim or human, i don't wish to kill anyone for no reason. I love humanity, and before killing a life i would think twice or thrice about their parents and how they gonna suffer from this killings and would they survive normally or its gonna be the biggest losing.. Killing a life would contribute to negativity on many sides, think of it how much their parents would suffer, their relatives, wives, and etc etc,, You are not only killing the soul, but the whole happiness of their family and their relatives too.
But then, if the only option for me to survive by killing then i would do so, this applies only to normal people.. but, in case if its a terrorist groups and those groups are amongst the cursed one like saudis, alqaeda, talibani, jews, american, ISIS, boko haram, then i wouldn't mind of self bombing over them whilst taking my soul away of it because i would be happy to die for the sake of thousands living and happiness.
To be frank, i am afraid of death, Everyone afraids of their death, even if its monster like brock lesnar or brawn strawman be it whatever it is, death will bring up fear into you. But then ill be ready to take myself off when i could contribute for others living.
One thing i would like to share to all of you is that, God Allah has not given any permission to anyone to kill unless for safety purposes. Man has not been granted any authority to take other souls off, unless if it is under the decision of the one owe's power in terms of community
Next, If death is the solution for everything, then the earth would lost billions of humanity on it. The best agenda is to live peacefully and love each others, when the killing is necessary, then commit it, otherwise do not
