If you can accept humans can eat helpless intelligent creatures, then the fact we perform ethics-reviewed anesthetised procedures and later dissect the same animals really shouldn't keep you up at night.
Not only we can heat... we stuff our faces into it several times a day and we keep rearranging the forms we eat it.
We even make an effort to make it more enticing to children in the form of small golden nuggets like it's some sort of a treasure of flavor.
Heck yea, it is!
The post was about human consideration of animals as a resource generally.
It's not much of an argument saying that since eating animals is a thing, (the comfortably narrowly selected example of) other things we do with them is no cause for questions.
