It may hurt economically by affecting things like aviation, but is unlikely to
directly cause any loss of life. Humans aren't very sensitive to indirect loss of life that only shows up in statistics. It's similar to blowing up Russian oil refineries and gas infrastructure, in that it will impact civilians, but unlike such attacks it won't directly kill civilians. If this already concerns you, you should be
very concerned about the economical sanctions imposed on Russia over this war, which have a much greater impact.
It's fine to have opinions over how wars should be fought and where to draw lines, but sadly implementing those opinions and having them survive contact with the reality of war is only realistic if all parties agree on the battlefield. We pretty much just have the Geneva Conventions for this, which Russia has been ignoring[1] anyways by attacking targets like grain silos.
