You pretty obviously can’t do whatever you want. From a legal perspective you’ll be arrested and prosecuted if you commit a crime. From a philosophical perspective you have a moral duty to do good, by virtue of the intrinsic definition of good (whatever that may be in your ethical framework). Even if your ethical system says you should only do what makes you happy, you still have a duty to fulfill that goal as it is internally equivalent to the concept of good.

> Look twice, and then once at anyone that tells you have a moral duty to do anything.

You are free to do whatever however moral duty does exist.

Being in tech means never having to say you're sorry (because you can freely switch between being a libertarian to shirk responsibility or a collectivist to shirk responsibility)
