@piggo indeed, weird questions and things one has in mind after seeing that. For instance:
- if the alternative weapon was artillery and they'd use 20 shells to deliver the same damage, would it be perhaps a better option? cheaper? Or more humane?
- seeing such cruelty a year ago would disturb me hugely. Now, after 11 months of watching these things and realising what it means for my own life, I don't even blink much - or perhaps wonder like you about the economy of all this. What does that even tell about me as a decent human being? (at least I fancy to consider myself one)

And so on. What a different world we live now... I never considered myself a pacifist, but I also never before thought I will feel certain satisfaction in some moments of a/this war. Yet I do. It changed many of us I suppose...
