A person can become a criminal intentionally or unintentionally. Either he deliberately does the crime or does the crime due to mistake or maybe because of pressures in life. A person kills anybody in an anger or dispute or revenge or whatever. There are even persons who can commit a crime by killing someone who has invaded his privacy while he is sleeping in the middle of the night.
