Well... "out of necessity" is actually an idiom, meaning "because you have to". Since need and necessity are very similar in meaning I assume this is a correct statement. But I'm not a native English speaker this may of course be a common mistake.

Regardless, I hope the idea stands.

Since we are trying to learn the tree language, I hope people don't get annoyed if I wonder about what is the mental state that converts "out of" into "because".

If necessity was a generator, a vector or force for movements or actions, then I could understand that use of "out of". Out of indicates the result produced by a force, algorithm or oracle. But I consider necessity not as a generator or force but as a passive state. Hence I wonder what is the mechanism for this use. If we collapse the concepts of passive and active then I think language get corrupted and poissoned. Analogies are not fruitful because they go far beyong the logical ground. I believe that if you are going to get something out of a state then that state should be a generator. I don't know if what I am trying to say is sound but I sharply feel the unsoundness of linguistic non logically generated derivations

There is a great explanation of the difference between 'because of' and 'out of' in an answer to this question on English Language Learners SE [1]:

> You should use "because of" in cases like this when the thing in question is the catalyst for something to happen, and use "out of" when the thing in question metaphorically "gives rise" to something else.

I always assumed out of necessity idiom means no other choice. And because of would mean I have choices and this is the justification for the one I made.

For the purpose of the comment "out of need" felt a lot more appropriate for an animal that kills.

Perhaps originally this use of "out of" indicates a mental state in which change is promoted, in which you fight against an hostile passive state, so you bootstrap from your needs.

Perhaps that kind of mental state could be used for sentiment analysis. The probability of that use of "out of" increases when you are in a mental state that promotes flipping active and passive states. For example, when you not any longer want to cope with your actual state, going to extremes: you put yourself in a fight for survival state that promotes a revolution by beating the slavery chains.
