Why does Sherlock Holmes abhor emotions?

A. Sherlock Holmes is a logical man and in many cases, Logic (Logos) and Emotion (Pathos) conflict with one another. In such cases of conflict, IF Sherlock Holmes valued and enjoyed emotions, then he may find it difficult to side with the "logical side of his brain".

Though, IF Sherlock Holmes rejects the thought of experiencing emotions and forces himself to remain as stoic as possible (as unattached to people, places, and emotions) - THEN, he can effectively, efficiently, and logically handle a situation.

In most of the cases that Sherlock Holmes works to solve, emotions have played a vital role one way or another. Whether it be that the killer acted out of blind rage (an emotion), or if a man stole a diamond ring out of pure greed (an emotion).

Everyone, for the most part, feels emotion of some sort or another. Sherlock Holmes, is able to (in most situations), control his emotions and put personal feelings to the side.

If a man is enraged with fury, he cannot logically form a solution to the problem that he is faced with.

If a man is mourning the death of a loved one, he cannot effectively motivate himself to attempt to solve the case.

If a man is madly in love with another, he may be blind to the truth that they are only manipulating him and his feelings.

I could go on ALL day about the reasons why Sherlock Holmes hates, detests, avoid, etc. emotions.
