How to destroy an actor by clicking a different actor?

I have an actor (lets call him tim). When I click that actor (tim) it creates another actor (lets call him bob). How do I make it so that when I click on bob it will kill tim? In my case I have an actor in the scene and when it is clicked a different actor is created in that same scene. The actor that was just created can then be clicked and it will kill the first actor. I am unable to achieve this because I don't know how to kill the first actor by clicking the second actor. Any help is much appreciated!

You have to create an attribute X in bob that has the value tim so that you can use an event when clicked on self, kill actor X. The image "part 1" should go in a click on actor event for Tim's behavior, and the image "part 2" should be in a click event in bob's behavior with an attribute MyActor or whatever you want to call it.

It worked perfectly, thank you so much!
