Firing rockets into Israel is one of the few ways they can actually do something. It's what stopped people in Sheikh Jarrah from getting evicted in 2021 if you remember that. And while many atrocities were committed on October 7th, we can't ignore the fact that it had clear military targets and goals. Or the fact that the IDF killed an unknown but significant number of their own citizens during their response to the attack. Your interpretation of the events of October 7th seems like it's based on early reporting of the attack; we know a lot more know and it wasn't as one-sided as Israel wants you to think.
