a. Tom must have done something to make you angry.
b. Tom must have done something so that you got angry.
c. Tom must have done something for you to get angry.
I think there are two possibilities here.
Tom did get you angry, but it is unclear whether that was his intention.
Tom intended to get you angry and did something with the intention of getting you angry. It is unclear whether he succeeded or not.
I think (b) corresponds to (1).
I think (c) corresponds to (2).
I think (a) would normally correspond to (2) as well, but the sentence is somewhat ambiguous. I am not sure all native speakers would agree on its precise meaning.
Is that correct?
Which of the sentences a-c imply intention and which are about the result of the action?
