It could be anything that I fear. It will harm me unless I take evasive action. Fear is my first reaction to the cobra on my path. I would be foolish not to fear it? No deep allegory intended.Who is the cobra? .
But many people engage in evil, whatever the reason. An assassin may think it alright to kill for pay but wrong to shoot someone in the back, while a priest may believe it wrong even to speak harshly. A thief may believe he has the right to steal to feed his children, a prostitute that she has the right to do with her own body.Why should we engage in evil. That is not 'dharma'.
