In the Forgotten Realms, are Druids fundamentally against necromancy?

In my group, we have an undead skeleton necromancer and a Druid. The Druid is very, very against necromancy and the undead because he is under the assumption of “that’s how Druids are role played because Druids worship life”.

I was under the impression that Druids didn’t worship life, but specifically nature. That and Druids are traditionally neutral. I would understand if the Necromancer was creating undead plant life, but is it mentioned somewhere that a Druid should be at least ambivalent to undead creatures if they are used for the common good?

This is in the Forgotten Realms setting.
