But hey, if you don't understand it, it makes you seem much smarter claiming it's brilliant instead of challenging it, I get that.
I think its a matter of survival, he knows it worked and he just wants to make sure its put into action by words. Reality is Ben is going to kill lock anyways, but fake locke doesnt know this so he feels the need to make sure he crosses his t's and dots his i's by telling richard to tell locke he must die.
Locke will die in his quest to get everyone back to the island regardless of what MIB says.
