Does it make sense for Druids to kill Gnomes?

[Wakanda]

When I was a little kid I would get upset because I would see Druids frequently camping the Gnome guards in Steamfont around the clock, and I couldn't understand it. Druids are supposed to be the good guys, and gnomes are good people ! So why are they killing each other?

But then when I got older it made more sense. Gnomes represent Technology, and Drudis represent Nature. Would the two not be natural enemies?
