Death
Reasoning for this riddle:
Salaam my friend, and hear my soft song,
calling the tired and lulling the strong.
Can be gentle, like falling asleep
comes to all life, weak and strong...
Lullabies fit from peasant to crown,
heard even by beasts and plants in the ground.
rich and poor... animal and plants
I rob cuts of their sting,
soothe cares the world bring
treat every hurt and bruise,
yet am a panacea few would choose.
Ends any pain, disease, or injury,
Will to live makes this the last resort.
Now scissors cut a thread in two
making way for youth anew.
A finger's touch, the world withdrew,
a gentle dance, just me and you.
Greeks depicted with the fate Atropos needed to make room for new life the "touch of death"
