The right to life is the belief that a human being has the right to live and, in particular, should not be killed by another entity. The concept of a right to life arises in debates on issues including capital punishment, with some people seeing it as immoral; abortion, where some feel an unborn fetus is a human being whose life should not be ended prematurely; éùthanasia, where the decision to end one's life outside of natural means is seen as incorrect; and in killings by law enforcement, which is seen by some as an infringement of a person's right to live. Various individuals may disagree in which of these areas the principle of a right to life might apply.
