In BG3, at least, if you are happy with the Oath-Breaker subclass, then it's easy to choose to do whatever you want as a Paladin ( choose any other subclass and make inappropriate behaviour a priority ), become oath-breaker, profit.
Add in a little berserker-barbarian frenzy to the mix for added damage, advantage on attack, more tankiness and another attack; divine smites are not spells, so you still get those while raging.
