Some people just kill mosquitoes recklessly??

Aside from the unavoidable consumption of animals for food,
we should refrain from killing animals.
If you are killing them for fun, or if it is not strictly necessary to kill them,
you should try your best not to.
Plants do not feel pain, but animals have nervous systems,
so they feel pain and suffering.
There is a reason why vegetarians exist.
Though I am not a vegetarian myself.
The other day, I went to a room cafe with a female friend (it was a bright, wholesome place). We heard a mosquito buzzing, and she clapped her hands
to kill it.
It completely turned me off. I told her that mosquitoes aren't of great help to humans, and even though they consume a small amount of blood,
unless they are malaria-carrying mosquitoes, they aren't a major threat to humans.
They are just a nuisance. There are clear ways to drive them out without killing them, such as opening a window or using a mosquito net, so if you kill them recklessly,
how much pain must the mosquito be in? If you put yourself in their shoes—if a giant being
crushed a human to death, the internal organs would be destroyed and bones would be crushed, resulting in death accompanied by unspeakable pain. Don't you know the concept of empathy?
I told her I was disappointed and we parted ways immediately.
After that, she told me I was the strange one, but I shot back that she was the strange one and went ghost on her.
