Lol...you mean how no one cares about killing dragon wyrmlings?
Or Hatchlings, yeah. They are "kids", right? Oh, I'm sure there are many advocates of all things draconic, but I've noticed far less hand-wringing over the slaying of the fire-breathing, lightning-hurling, acid-spewing, poison-belching and cold-exhaling menaces even when they are merely man-sized.
You're wrong. We just haven't gotten to it yet. 🤣
But while we're on the subject... Dragons ARE intelligent and not all Chromatic have to be evil. Right? Oh. But they have four legs, so it's okay. 😁
They are Evil (Lawful or Chaotic) in AD&D/AD&D 2e and "Always lawful evil"/"Always chaotic evil" in 3e/3.5e. Starting with 4e, D&D started to go soft on monster Alignment in general.
