Should Vettel be banned?

You can never fully judge intent. No one actually knows if Schumachers intent was to take JV out 100% except Schumacher.

Sure you can judge intent - The Man On The Clapham Omnibus test.

1. Would a reasonable person have forseen the natural and probable consequence of those actions?
2. Could a reasonable person have foreseen that result, with reference to all the evidence?

Sure, no one actually knows if Schumacher's intent was to take JV out 100% except Schumacher but you can ask if a reasonable person based on the evidence could have forseen it.

Aside: Everyone knows what Senna's intent was at Suzuka in 1990. He said as much before the race. He should have been banned forever.
