RED - I am good or bad ?

I am in danger,
I am in anger.
I am in blood,
I am in flood.
I am in sun,
I am in burn.
I am in spark,
I am in dark.
I am in fire,
I am in liar.
I am in sin,
I am in gin.

I am in pure,
I am in cure.
I am in win,
I am in virgin.
I am in love,
I am in above.
I am in temple,
I am in people.
I am in god,
I am in Umbilical cord.
I am in vein,
I am in brain.

I sometime wonder,
I sometime ponder.
I am good or bad, I sometime think.
I got no answer got no link.
