Beyond Right & Wrong
There are no "right" or "wrong" actions. Only actions and their consequences. And these consequences may be perceived as desireable or undesireable (depending on our situation and perspective).
When we use "shoulds" we speak from value judgements and an (implicit or explicit, consious or subconsious) ideology. We have an attachment, which is often unconsious and leaves little choice.
When we use causality (action X may lead to action Y), there is more precision, consiousness and choice. It leads to simplicity and often more pleasant interactions.
