In a manner that is free from guilt or blame; without any sense of wrongdoing.
From guiltless + -ly (adverb suffix). This combines the adjective guiltless with the adverbial suffix to describe actions performed without guilt or conscience.
Guiltlessly describes a kind of pure action—when someone acts guiltlessly, they're doing something with a completely clear conscience, which is rarer than you'd think in a complex world where most actions have moral gray areas.
