Are small snails good for plants?

Question

I found a snail on my aloe vera plant, are they good for plants or should I smite it like God smote the heathens of Sodom and Gomorrah?

Answer 1

Snails are very bad for plants, not all plants. They can devour a whole plant. They ate my Hosta's.  

Answer 2

I would get rid of it before it has any chance of destroying the plant.  Here's a couple of sites you may want to check out. Good luck.
