@saredochani10 my sister you must understand self defence is a fundamental right, which means that when your being threatened by people who have no remorse that they would target innocent people who have nothing to do with gang/urban culture but live in a poor area as well as a seething hatred fo us that they would go to the extent of killing indiscriminately, then you must realise that will go to any lengths to defend their loved ones put the illicit nature aside for a while by illicit I mean the actual sin/crime of murder but think about any person wanting to defend their loved ones which is indicative of all of us irrespective of gender, age, culture, religion, this selfless act something we all believe in which is not just our own personal survival but that of our families/community too, if may Allah forbid you found one of your relatives being attacked wouldn't you want to protect and defend them after all its a greater sin to not do your duty of safeguarding those who are closest to you whether its your family or cultural kin when your capable of doing so please understand the difference between killing for self defense and killing for the sake of killing which even is discussed at length within the quran & Islam for example their is a verse within the quran that says as follows " kill them wherever you find them " which is deemed as controversial because its a verse Islamophobes cite regularly to imply that it actually refers to non muslims particularly jews, christians, which isn't true but certain interpretations of these verse have been explained to mean that it actually refers to no specific religious group but in fact those who spread corruption in the land that can have catastrophic repercussions which can also mean a high death toll perhaps due to turmoil therefor one can infer that killing could be condoned to perhaps end all the significant loss of life due to destabilization at least some of which is my thinking regarding what the meaning of this verse maybe and its understanding in essence you must realise murder particularly murder for altruistic reasons isn't out of the norm for many societies, your from france I'm sure your aware of the confrontations that happen between maghrebi's and blacks which can unfortunately lead to deaths.
