"An African Proverb: the child who is not embraced by the village will burn it down to feel it's warmth."
This is a dangerous proverb and could be used to justify a number of violent acts.
I am not saying saying looters are the same as the following examples but that the proverb can be applied to them to.
School shooters, the ones who don't do it for fame obviously as there are 2 main categories, are shown to have been disenfranchised, bullied, harassed by other students, ignored by teachers and the like when they've asked for help or clearly been distressed and the shooting is retaliation against the people that have marginalised them. I feel desperately sorry for these individuals but it absolutely does not justify what they go on to do.
People who go on to kill their child's murderer when they get parol. Their actions were obviously abhorrent, there is no relief from the loss of a child, they may feel failed by the justice system. However they are still wrong to them commit murder themselves.
Abused children who enact physical violent revenge on their abuser later in life once they have escaped the abuse (I.e. not at all in self defence). Their reasoning is completely understandable, they were not embraced but actively harmed by the person. However their action of revenge is still wrong.
Again I am not comparing these to the lootings, they are different situation with different consequences.
I am saying this proverb is dangerous in that it could justify all of these.
