This isn’t just a matter of vague speculation as there are historical cases outside of Israel on which to see how things like this develop and what the consequences are both for the victims and the soldiers. These historical accounts also indicate soldiers committing these sorts of actions become victims themselves with catastrophic mental health disorders.
Israel got in trouble with ICJ court, because of quotes from top government officials. Government of Israel was very specific what they will do to Gaza! This was even full scale bombing started!
Trying to reinterpret this as a problem of "military discipline", and "soldiers are victim as well" is just another level of cynicism!
