In State v. Dixon, 283 So. 2d 1 (Fla. 1973), this Court provided the following definition for the HAC aggravator:
It is our interpretation that heinous means extremely wicked or shockingly evil; that atrocious means outrageously wicked and vile; and, that cruel means designed to inflict a high degree of pain with utter indifference to, or even enjoyment of, the suffering of others.
What is intended to be included are those capital crimes where the actual commission of the capital felony was accompanied by such additional acts as to set the crime apart from the norm of capital felonies-the conscienceless or pitiless crime which is unnecessarily torturous to the victim. Id. at 9.
