I am a part of life that hurts because I am not always fair.
I can make you feel betrayed; I can make you feel aware.
"I will never lie to you" is the eternal motto I proclaim.
Give me thanks, that's big of me but, I will hurt you just the same.
Someone who lives with me, will always stand in your defense.
To speak with veracity is using me at someone else's expense.
I have been known to cause trouble and I often get in the way.
To ignore my existance is sinful, so be careful what you say.
To have a healthy personality, I hear, I am a must.
If I ever stear you wrongly, it is the fault of my brother, trust.
If you don't have any morals, no purpose will I serve.
However my sister conscience will give you what you deserve.
Those of you that are blinded and ignore my existance,
Know that it is morally wrong to be willingly innocent.
Do not stand aside and wait for someone else to work your will.
Express your true colors so the angered may know who to kill.
If you swear to me, I will protect you as long as you dont lie.
Now I ask you with all with pure intent, who or what am I?
