Invalid logic pertaining to karma in sutta AN 5.129?

**WARNING: I don't hold the views put forward in Section B (by "the views put forward in Section B" I mean everything in Section B besides the sutta itself.) of this question anymore and I think that the views should not be held by anyone because of them being dangerous. It's dangerous to believe there are no bad consequences for one for doing some intentional bad(e.g. violent) action/s. It's much safer to believe there are severely bad consequences for one for doing any intentional bad(e.g. violent) action/s. I now believe that every intentional bad(e.g violent) action that one does does have bad consequences for one.** Section B: This has been perturbing me for a while. --I have noticed what looks like invalid logic in this sutta https://accesstoinsight.org/tipitaka/an/an05/an05.129.than.html ( note 1: this is the conclusion I come to if I look at kamma and the the-fruit-of-kamma (vipaka) logically, if it isn't true then it seems kamma and the-fruit-of-kamma (vipaka) operates illogically or "randomly" or in an unknown way??? note 2: The paragraph below also only seems applicable if the event is onesided i.e an "innocent victim" is involved ) Seemingly the aggressors are supposedly in hell for their actions but weren't their actions (the aggressors) only because of their victims kamma from past lives (now their current fruit-of-kamma (vipaka)) and therefore the aggressors actions (the victims fruit-of-kamma (vipaka)) were seemingly unavoidable, so why would the aggressors be in hell?
