It s that simple. Random behavior isn t very effective for achieving goals. Not only that, an inability to distinguish good from bad is what drives people crazy. We all know about bad things. Bad things hurt.
Bad things cause pain and suffering.
Bad things lead to degradation and death. Bad things disrupt the orderly nature of our minds and bodies, twisting them, distorting them, changing them into something that serves another purpose or no purpose at all. When we identify a bad thing we want it out. We want it to go away. Out and away.
