Commentary
Consecrating or dedicating one's actions to God is sometimes given a weird twist of interpretation. The warriors of the ISIS in Syria raped thousands of captured women, sometimes in the presence of their husbands. Before raping, however, they would prostrate themselves on the ground, pray and dedicate their act of rape to God, and then engage in forcible sex so that they would incur no sin.
Immoral actions must be avoided; dedicating them to God to stop incurring sin will not do. The Bhagavad-Gitā, to preclude such misinterpretation, distinguishes between desirable and avoidable actions. The Lord clarifies that one must understand the difference between "actionlessness" (akarma), action (karma), and sinful actions (vikarma) (4:17). Rape is a vikarma and dedicating it to God while engaging in it will do no good, and won't save one from damnation.
