This paper reviews various life-ending techniques such as euthanasia, suicide, and assisted suicide in order to better address the psychological issues related to these actions. Specific attention is paid to investigating when a death is deemed to be appropriate and the role that the level of appropriateness should play in the decisions of individuals to terminate a life. In addition, a number of additional psychological concepts such as locus of control and subjective norms are examined in terms of their importance for decisions regarding euthanasia and suicide.
