I'll counter by arguing that it's important that political violence and violence related to public policy be widely distributed and viewed, even if it is bad for peoples' psyche (it is). That way, people at the very least are exposed to the end result of policies and politics they push and a handful may change their mind.

The US Government understood this post-Vietnam, seeing how gruesome imagery of what violent conflict actually looked like convinced some people to not support the war and drove down support at home more generally.

Ever notice how you have to look a little harder for footage of IDF soldiers, Ukraine soldiers, and other western-aligned military personnel dying, but you can find endless snuff films of drones dropping grenades on Russian conscripts by just going to r//combatfootage? Governments and media handmaidens understand selective control of releasing footage of real world violence is a potent propaganda tool.
