Your evidence supports that there are members of the IDF who are enthusiastically engaged with what they're doing. I am not debating that- i think you're right.
But it's important to remember this absence of evidence is not evidence of absence. Just because you haven't seen interviews of IDF members objecting to what they are doing does not mean those members do not exist. I would expect the IDF to have systems in place to minimize the external visibility if any such objections, which makes a generalization like that dangerous.
