It's kind of hard to have finishing moves on every guy when you are being attacked by five people. You will take unnecessary hits.
It will probably even rile the guys making multiple guys able to attack you at the same time. It's kind of like showing off before the fights are finished.
The hits doesn't really matter in "God Mode".
Five tamed animals are crazy but fun.
In my opinion that's what the Animus Control Panel is about.
Have some fun with crazy stuff.
