I agree with you that it needs to be clarified further. While I think it is still “resistance” in the sense that it was done with the intention to resist occupation and all what Israel does, I do agree that civilians died that didn’t need to, and it did not lead to positive results.
When you live your whole life in a concentration camp and get bombed almost daily, you may lose some rationality and start justifying more things in the name or resistance. Ultimately I blame Israel for putting them in this situation, and putting civilians so close to their border.
In the end, my whole point is that Hamas attack must not justify a response from Israel. It should lead us to pull back instead.
