> Whoever, with intent that another person engage in conduct constituting a felony that has as an element the use, attempted use, or threatened use of physical force against property or against the person of another in violation of the laws of the United States, and under circumstances strongly corroborative of that intent, solicits, commands, induces, or otherwise endeavors to persuade such other person to engage in such conduct, shall be imprisoned not more than one-half the maximum term of imprisonment or (notwithstanding section 3571) fined not more than one-half of the maximum fine prescribed for the punishment of the crime solicited, or both; or if the crime solicited is punishable by life imprisonment or death, shall be imprisoned for not more than twenty years.
Intent is also one of the key factors that distinguishes between different categories of murder - it varies by jurisdiction, but generally premeditated murder (you intended to kill the person in advance) is different than a "crime of passion" (you intended to kill the person at the moment you murdered them), which is in turn different than an "accidental" murder (you didn't mean to kill the victim, but you did).
