once a thief always a thief
a thief once will always be a thief why i am saying this? because it's human nature: you can do everything for someone, try to change yourself for them; they can try as much as they can, but the thing we call fitrat can't ever be changed.
this is where you have to find peace that they will ruin everything for themselves. and there is nothing you can do about it.
not your gamla not your phools
