Technically wouldn’t being a democracy be an aggravating factor for Israel wrongdoings, which makes the population more responsible compared to Russian or Belarussian one (therefore including athletes)?

I don’t really agree with the rationale, although I personally wouldn’t have supported a ban on Israelis athletes (similarly to how I generally don’t agree with the same ban on Russian athletes - unless you are specifically a supporter of values that go against the Olympics such as genocide…- e.g., I agree with Karjakin being banned from any chess competition).
