Everything that concerns the Israel/Palestine conflict is highly controversial, and naturally this incident has made people on both sides employ their usual set of rethorics.
I acknowledge that there are two sides of the coin here, but one important fact is that Israeli soldiers bordered the vessels on international waters, which is naturally beyond their jurisdiction. If they faced resistance because of this act, they're not really entitled to complain. And as they ended up killing up to ten passengers, whatever mitigating circumstances they can bring up are pretty moot in the big picture.
