Who am I? (part 2)

Just had another thought of myself, which is also among something I say many times to a lot of people.

I am a good person

But not many people believe me ... so I continued with

When I told people that I'm a good person, no people would believe me and say I'm a bad person... so I do what I am expected to do ... do bad MUAHAHHAHAHAHAHAA~~~~~ but deep down... well i'm not good but i'm not that evil either... i'm just playful, childish and slightly naughty.
