Whether somebody can be considered evil depends on their intent. I believe that most people would give up animal products if they felt they could do so and sustain the new diet. What farmers do specifically is down to them, not the consumer. The only responsibility the consumer has is for the death of the animal because their diet requires it, but not feeling able to be vegan is a much deeper and more complex issue. We should remember where we came from before judging others!
>"What farmers do specifically is down to them, not the consumer."
No, farmers do what they do because consumer spending habits dictate what they have to do to stay employed. The consumer is most primarily responsible for the animal suffering.
In the case of cutting the testicles out of pigs, the reason farmers do it is because pigs that have not been castrated develop what is called "boar taint" in the meat, which gives the meat an undesirable flavor consumers don't enjoy as much. The farmers who don't castrate pigs apparently have difficulty selling their meat and don't tend to stay in business. Thus, the practice is widespread throughout this industry
because of consumer purchasing decisions.

The vast majority of people can be perfectly healthy on a vegan diet. Most people eating a whole food plant-based diet would see their health improve dramatically. They do not "require" meat to be healthy.
>"not being vegan is a much deeper and more complex issue"
Not really. Most consumers make their food purchasing decisions primarily based on taste and price. They want something that will excite their taste buds and save them money. If products like Beyond Meat and Impossible Foods were priced lower than comparable animal products, their sales would increase dramatically as these alternatives take sales from animal meats.
It's a mix of gluttony, greed, overindulgence, and the prioritization of "instant gratification" over the long-term health benefits from a whole food plant-based (vegan) diet. Not to mention the suffering of the animals and the environment..
