I had that moral dilemma when I once did an answer to a post here where I explained how to cover your tracks with alternate emails, computer logins etc. My wife told me "you are helping others deceive their wife". I said "yeah, but also avoid their young children finding out" (children were mentioned in the thread). She said "yeah but also the wife". I munched on it for a few minutes and decided that she was right and I deleted the post.
Btw there is no way you can recommend a good place for hiding inside another's house because that thing is the least universal thing in the world. How good a hiding place is mostly depends on who lives there (and who visits, too) and their exact habits and you don't know the first thing about them. So I would say that taking any advice here on that topic is a probable recipe for disaster with a variable realization delay.
