It's kinda hard to follow an argument when the goal posts keep shifting.
If the purpose of the attack was to make a point, to raise awareness, to break a stalemate, or to disrupt normalization between Israel and Saudi Arabia, then a limited strike on the IDF bases, and capturing soldiers as hostages would have sufficed. It would have humiliated Israel while at the same time resulting in much less international backlash toward Hamas. It would also rob Israel of much international support and justification for retaliatory actions.
I did not suggest that Hamas had to go butt heads with the IDF. Nothing about symmetrical warfare. Just that the atrocities part, the attacks on civilians and so forth were not necessary.
I've no idea which questions you think I haven't answered. I know you didn't answer mine regarding the two-state solution (both on this topic and another one).
