Difference between にとって and として?

Question

What differences are there between にとって and として ? To the best of my understanding, both have meanings of stating something from a certain point of view or perspective. However, I think that there's some kind of nuance/grammar pattern between them that renders them noninterchangeable. For one, I guess it's ok to say > 僕にとって、これは大嫌い。 > 人間として、人殺しはいけないことだ。 But you couldn't reverse the two to say > 僕として、これは大嫌い。 > 人間にとって、人殺しはいけないことだ。 Intuitively, I'm thinking it has something to do with volitionality?

Answer 1

It's points of view.

僕にとって、これは大嫌い。 As for me personally, I hate it. (from my specific point of view)

人間として、人殺しはいけないことだ。As human beings, we should not kill. (in this particular role)

僕として、これは大嫌い。 <<No particular role to fill, cannot do>>

人間にとって、人殺しはいけないことだ。As for human beings, they should not kill. (sound unnatural, but you can use it this way)
