Murder, suicide, rape, and abortion are all leading to the same thing - you are taking a person's life away in one form or another. With murder, you're taking a life, with suicide, you're disrespecting and throwing away a life you were given, with rape, you're permanently damaging someone's soul, and with abortion - you're taking away a potential life. I regard all four as heinous acts that are almost never justified. You were given this one life to live -respect yours and respect others'.
Robbery, fraud, stealing, and drugs fall on a lower level than the above mentioned, in my opinion.
