I am trying to define the word "deceive". In English, I would say something like this (regardless of whether or not it is a good definition):
To deceive someone means that you lie to someone, and without regard for their well-being, you gain something for yourself.
In Japanese, I would translate from the English to
In English, we have this "you" that does not really refer to a specific person/group. So I can't just replace 君 with a name here. Is an alternative word used in Japanese for definitions (similar to 相手 meaning someone)? If "you" is appropriate, which form of "you" should it be (e.g. 君, あなた, ...)?
If it matters, I am more concerned about how this works in speech, not writing.
