Wittingly
Done Purposefully
Use 'wittingly' to express actions made with intentional awareness or decision, opposite of accidental. 
Emphasized Intention
'Wittingly' adds emphasis to the deliberate nature of an action - more than just saying 'on purpose'. 
Not Always Positive
While intentional, 'wittingly' doesn't imply the action is good or bad, only that it's done knowingly.
