"Motive" may be defined as that which actuates or influences, that which determines choice. It implies the presence of an uuimpaired will power, at least one that is not so seriously impaired as to be incapable of volition, and actuated either by right or wrong desires.
Impulse is the sudden application of some powerful motive, that causes the will to act hastily without usual deliberation, or that exercise of the reasoning faculties that occurs when a purpose is deliberately formed. The genesis of impulse may be a good or evil motive.
In both instances either when the act results from the motive operating upon the mind through a deliberate and logical course of reasoning, or impulsively, as when the motive acts independently of, orsupercedes and dethrones reason, if it attempts to assert itself in either instance, there is one condition that is common to both, and that always is present,
