Why do so many killers plead for their lives when they had no mercy themselves?

They take the life out of someone but expect to be given a life sentence and not the lethal injection. Ironically, they had no mercy for the victim and several of them even killed in a horrible manner.

As a child I remembered the earliest example to this irony is even seen in the Disney movie The Lion King 1994. The evil uncle Scar pleading Simba for mercy ''Simba please have mercy I beg you... but I am family... what are you going to do? You wouldn't kill your OWN UNCLE?

Yet, he threw his OWN BROTHER (his own flesh and blood) off a cliff and had no mercy nor remorse for it ever. He killed without hesitation but wanted to be given mercy. Why is this found in many murderers?
