They still visibly sprout flames in their design. You don't have to be literally hotter than the sun to be a fire hazard.

They have tried though, like, in several episodes. They don't succeed because the anime isn't that dark, but it's still Japanese not-that-dark. The anime is fairly shaky on what they think of Ghost Pokemon in general - well, especially Ghost Pokemon - because it largely depends on the needs of the story.

The only episode i can think of was the Lavender town one and there was no maliciousness there.
