Peter puts a foreign substance in Jeffrey's wine with the hope that Jefferey will drink it, feel ill, and vomit. If Jefferey drinks the wine and dies, is Peter liable for an intentional tort? Why or why not?

What if Jeffrey asked Peter for a glass of wine, and Peter gave him a drink that he (Peter) reasonably believed to be wine but was actually poison and Jeffrey died- is Peter liable for an intentional tort? Why or why not?
