So, the only reason people have a problem with AoO and Cleave is becasue there might be an encounter in which the bad guy kills his own people to attack the party? Seems like a weak reason to dicount something in the rules.
You missed three out of four logical possibilities. The full array is:
(1) BBEG kills evil mooks to attack party.
(2) BBEG kills good mooks to attack party.
(3) Hero kills evil mooks to attack BBEG.
(4) Hero kills good mooks to attack party.
With the use of summonings a hero may kill good mooks without alignment problems. (It gets even more exciting if we add in third parties, e.g. neutral mooks, innocent bystanders, co-allies, co-enemies.)
The idea of distinguishing between "allies" and "enemies" is purely artificial and illogical. Mechanically speaking the relavant question is who do you
choose to threaten or affect with Bless/Bane. It seems to me that the DM dictating who is or is not my enemy/ally is as extreme as railroading can get.
As far as the aboves reasons being weak, I am sure a lot of people agree with you. I am fine with that although my personal opinion differs. IMNSHO it is positively foolish to house rule case #4 while leaving #1, #2, #3 as is.
