Jack-o-lantern: good or bad?

Jack-o-lantern light,
Staring out at night,
With it's evil stare,
Or it's scary glare,
Is it there to keep away evil?
Maybe not, maybe yes,
Maybe that Jack-o-lantern's up to no good.

Scaring children throughout the night,
Looking through it's triangle sight?
Orange, evil, scary?

Look again.
It's just a jack-o-lantern.
