Homicide or Suicide?

(Man on his deathbed to his wife)

Sing with me O babe, sing with me
I crave for it, like I crave for thee
Your voice that tinkles, sounds heavenly
To hear, I’d love to wait till eternity.

Walk with me O babe, walk with me
As you walked, from the day wed we
These are the last steps I will take
Happy and jolly they be, sure you make.

Smile with me O babe, smile with me
Together let’s fight out this grief and pity
I need none of that when you are near
As no Satan, no pain in this world I fear.

Dance with me O babe, dance with me
Like you danced under our apple tree
Mortals are we and I win the old bet
Now, it is a farewell I deserve to get.

(Woman to herself)

I had twenty-four hours before I’d die
And I desired to never see you cry
I know, more than your life you love me
Poisoned you, for you'd shatter without me
Please forgive me, I love thee!

(Man to himself)

I knew you just had a day more with me
Understood, when you poisoned my tea
I felt sad for you, but happy for me
You were the best I ever had with me!
Please forgive me, I love thee.

P.S: Is it justified in the name of love?
