A person is reckless or acts recklessly, when he consciously disregards a substantial and unjustifiable risk that circumstances exist or that a result will follow, described by the section defining the offense; and such disregard constitutes a gross deviation from the standard of care which a reasonable person would exercise in the situation. An act performed recklessly is performed wantonly, within the meaning of a section using the latter term, unless the statute clearly requires another meaning.
