A deadly Thing

Love can be a deadly thing.
Causing murder, suicide and insanity.
Making the strong weak
the weak, strong.
Making heaven here on earth
And hell.
The stuff upon which dreams are made
and nightmares, torment and misery.
A marvelous partner
And a venomous worst enemy.
A factor in the world of hate.
Few should give up seeking it
And you know who you are.
