In "The Monkey's Paw" by W. W. Jacobs, do we understand that when man's fate is controlled by man, fate gets him bad ends?

Perhaps the message of W. W. Jacobs's short story "The
Monkey's Paw" is not so much that when man controls his fate there
are disastrous results as it is that when man thinks he is in
control of his own fate, there are often effects that he fails to consider that can
cause disastrous results.  A reexamination of the three wishes of the Whites will attest
to this statement.

For instance, when Mr. White makes his
first wish for two hundred pounds, he does not specify how he should receive this large
sum.  Left to chance, the results are devastating to the White family, since the money
is attained frim the insurance policy on their son's accidental death.  Then, when the
disconsolate parents cannot bear to be without their son and wish for his return, they
again do not predict all that can happen and, as a result, their wish is not specific
enough to prevent the grotesque and horrifying result.  It is their final wish that
comes true as they have hoped because there are no variables of chance allowed in this
wish.
