'坏' emphasizes a state of damage or failure (e.g., 电脑坏了 'the computer is broken'), while '不好' means 'not good' in a general sense (e.g., 这个主意不好 'this idea is not good').
When used as a verb (e.g., 食物坏了 'food spoiled'), it often implies a natural process of decay rather than intentional damage.
From Old Chinese '敗' (OC *brats), meaning 'to ruin' or 'to decay'. Evolved into modern '坏' with similar meanings.
坏 is a very common adjective in spoken Chinese. It can describe physical damage (e.g., 坏了), moral corruption (e.g., 坏人), or general negativity (e.g., 坏天气). In southern China, '烂' (làn) is sometimes used interchangeably with '坏' for objects.
