Over half of Palestinians are under 14 and most of them have never seen an Israeli in real life. Abused and mistreated does not begin to cover it. You're the one whose naively trying to moralize this. When you treat people like animals they behave like animals and "mistreatment" to this degree creates very dangerous animals. Whether the individuals concerned deserved it is immaterial, this is the consequences of their governments actions of which they were entirely complicit.
