How does Dr. Jekyll interpret his relationship with Hyde?

Dr. Jekyll does not repudiate his kinship with his alter
ego Mr. Hyde. He seems to have a certain feeling of affection for this other individual
because he recognizes him as a kindred spirit. This is not uncommon in human relations.
A man who is honorable, civilized, public-spirited and law-abiding might be attracted to
another man who is entirely different, who rejects conventional morality and lives to
please himself. This kind of hedonistic, irresponsible man can lead an otherwise sober,
industrious and trustworthy man astray, and even eventually lead that man to his utter
ruin. The same thing can happen to women who are led astray by men or by other
women.

In Shakespeare's Julius Caesar, the greedy, crafty,
selfish, and miserly Cassius says to himself after his interview with the noble
Brutus:

Well,
Brutus, thou are noble; yet I see

Thy honorable mettle may
be wrought

From that it is disposed. Therefore it is
meet

That noble minds keep ever with their
likes;

For who so firm that cannot be seduced.
(I.3)

Dr. Jekyll may be
naive, like Brutus, or schemeing, like Cassius. They are easy to victimize by inferior
men. Both come to tragic ends.
