Intent?  What does the jury believe his 'intent' was, based on all the circumstances?

Intentionally, Knowingly, or Recklessly?

"Under Oregon law, a person commits assault in the second degree if he:
intentionally or knowingly causes serious physical injury to another person
intentionally or knowingly causes physical injury to another person with a deadly or dangerous weapon, or
recklessly causes serious physical injury to another person with a deadly or dangerous weapon, acting with extreme indifference to human life. (Or. Rev. Stat. §163.175.)
Assault in the second degree is a Class B felony in Oregon."
