I guess that is your understanding of it ie about my own personal viewpoint, Im explaining it from a "moral" perspective though. From the viewpoint of knowledge between good and bad, you have to know what good is to know what is bad and vice versa.
If everyone around you became immoral and you were trying to keep your morals clearly your own point of view could be argued, but fundamentally on the principle of what morals are judged by good or bad, much like a compass, you have to know north is not the same direction as south.
Your effectively watching society move in one direction (together......as individuals making up a whole collective) while your aware you want to move in another direction. One example might be say, your told you have inalienable God given rights, but when you try to excercise them your clearly made aware you only have societal priviledges, or to be clear...your told you are "free" but if you try to walk out of your country your stopped, searched and held back or prevented. While this might be my viewpoint to agree on acknowledgement, it is fundamentally self evident.
Depression might come from learning you have no ownership rights, no autonomy on your ability to provide your own water, food, housing or medical care for others, your ability to secure gainful income is electronically prevented via your national insurance number, or your ability to eat good healthy food is reduced to which supermarket you can attend or what your budget allows, or how they are all linked together.
There are thousands of examples where your choices are reduced to which side door, left or right, you want to enter the slaughterhouse, but your choice to be left alone to your principle moral guidance to no harm or loss is not recognized?
