things were also the same around here, some thieves who got caught red handed sometimes also get a severe punishment from the people including the burning. I am not really agree also, yet sometimes those thieves also don't hesistate to take the victim's lives when they are able.
Just a sad reality in this world.
It's really not fair to me that anyone be punished that way no matter what the person did... It's best to let them suffer being alive and reflect on what they did wrongly
