Go look up pictures from Bucha where Russians placed triggered grenades under live babies in their dead parents arms so that the rescuers and baby would be blown up. Or how about the the mass graves found in Lyman. After seeing those tell me if you still feel the same way as you do now.
You're not exactly wrong, but from the POV of the people making the videos it is earned. When you see your friends getting killed on purpose, or whole cities of your home being destroyed, you have to develop some coldness and a sick sense of humor if you want to survive mentally and keep getting up for the fight day after day.
Like I say, you're actually sort of right I think from the POV of most of the people in this sub, but that's not the people who are making these videos.
