Those flowers were planted and grown so that they could be cut and used for pleasure.
Just like any other plants on this planet...
Sometimes you eat them, sometimes you drink them, sometimes you smell them, sometimes you smoke them, sometimes you use them as decorations, sometimes you make oil out of them, sometimes you make a fragrance out of them, sometimes you use them to make cosmetics, etc.
I would rather receive a (dead) bunch of flowers for my birthday that I can place in a vase and enjoy them while they last than pots and pots of living (breathing) flowers who are connected to the soil whose death is a certainty anyhow

In fact I am curious to know how much shorter is their life when brutally murdered?
I like the blue flower - love in a mist. Very nicely captured.
