If you lost it, you are dehumanizing people, which is a condition that many absolutist regimes aim to accomplish to enable genocide.

The Russian war of aggression and uncounted war crimes against Ukraine are suitable to make everyone furious, but how we treat even mass murderers is a reflection not of who they are, but who we are. By doing more than the necessary (and if that is killing, by being excessively cruel, or enjoying the killing), we harm ourselves, not the enemy. Because we desensitize ourselves to violence, and we become that which we claim to be fighting.

Support Ukraine with everything we have, but let us enable them to kill as cleanly as possible - that also means (looking at you, my government in Berlin) to give them proper long range missiles. Let us never rejoice over unnecessary cruelty towards anyone - although we may be happy for neutralized threats.
