It still strikes me as bizarre that a capo would be sent to perform the hit, when they have a ton of soldatos who would be much more appropriate, but maybe from a dramatic POV it's to show that Mike by the end of II has isolated himself from everyone except the cold, murderous Al Neri and Connie who's got nobody else. Even Rocco and Hagen were out. Part of the tragedy, methinks 
Joolsie, I tend to agree with you. Dramatic effect was probably the highest on FFC's mind. If you see the entire part 2, you will find MANY such instances - pentangeli's suicide following the conversation about roman empire, Kay's aborting the child, Fredo betraying his brother etc.
