In regards to eating meat

[βαθμιαίος]

Billions of creatures in constant agony

When you say this, what are you thinking of exactly? Because most cattle that I know of have good lives for the most part. They graze and are looked after. For grass-fed animals, that's all they know. There is no constant agony. Typically they go to a local abattoir on the last day of their lives and are treated well until the very end.

If the animals are sold to a feedlot, it's not for their whole lives but rather for the last few weeks of it. If the feedlot is well-run, the animals are not in misery there, either.

The part that gets all the attention, the slaughterhouse, can indeed be troubling, but slaughterhouses can also be well-run and minimize animal suffering. The animals are there for a matter of hours, not days or months.
