Israel makes mistakes and have very bad policies. I am the last one to defend it.
However, IDF is not a murderous organization as you think of it. There are clear rules on how to engage in combat and strict written moral rules that everyone should follow. I know because I served there and was taught these rules and had to memorize en.m.wikipedia.org/wiki/IDF_Code_of_Ethics
However, people are people. There are bad apples. People also just make mistakes and Israel has (too) many different opinions and fragments and ideologies that I have nothing in common with. So yeah it’s complicated.
Your view of Israel as one murderous genocidal entity is not different from the view a lot of Israelis have of the Palestinians, especially after October 7th, that is sad and will not bring the conflict anywhere to an end
