While raged, if you choose to attack,,you must make a Wisdom saving throw. You may choose to fail the save willingly. On a success (DC 14), you are able to attack as per usual. On a fail, however, you will fall under influence. While under influence, you will be made to choose a creature on your turn as the target of your rage. Once you choose a creature you will do everything you can to kill that creature. You may change your target on your next turn. Your Rage damage dice and proficiency bonus is doubled while under influence. Each time on your turn you may choose to resist the influence by rolling another Wisdom saving throw at disadvantage. On a success (DC 14) your rage forcibly ends, leaving you with a point of exhaustion. Otherwise, you have no way to willingly end your rage and remain under influence until your rage naturally ends.
