I think that building a military camp next to an elementary school is the most condemnable thing.

Using civilians as "human shields" is not only immoral but also constitutes a war crime. According to international law, the use of human shields is explicitly prohibited. For example, Additional Protocol I of the Geneva Conventions prohibits placing civilians in front of military targets to prevent attacks, which is considered a war crime. This disregard for human life and treating civilians as tools is completely contrary to modern civilization and morality, and should be condemned by all of humanity.
