The behaviors described—such as soldiers posting images of themselves in diapers, stolen lingerie, and engaging in sexual acts in conflict zones—are seen as morally reprehensible. These actions:

Disrespect human dignity and privacy, especially through the appropriation of personal items from looted homes.

Violate military professionalism and ethical conduct expected in war zones, reflecting poorly on the military's image.

Could indicate psychological issues or moral disengagement, where soldiers fail to recognize the humanity of civilians.

Might lead to significant public and international backlash, with such conduct potentially breaching military codes and international laws.

Calling these soldiers "sick bastards" might be seen as a strong moral judgment reflecting societal disgust, though it's a colloquial expression of broader ethical condemnation.
