That is an oxymoron. You can not have respect for the animal and fully support killing it and all this without a hint of remorse or empathy. I can not comprehend how that would work.
For the sake of argument lets imagine there is such thing as "humanely" slaughtered cow. For example this one here, enjoying the sun: https://i.redd.it/9v0shahwsh921.jpg
First of all, cows live around 20-25 years and are slaughtered between 18 months and 3-4 years when it comes to dairy cows (which live a live full of misery and are disposed of, once they stopped producing enough milk to be economically viable). Best case scenario, you steak was a child/teenager in cow years.
Second, even the the most "humanely" slaughtered cow has to bleed to death for you steak - we don't want our precious meat to be soaking in blood don't we.
Third, your steak almost certainly didn't have a good live. If you want to see what humanity looks like at its worst, look no further then any industry involving humans and animals that can be economically exploited. Dairy, meat, eggs, fur, wool - it is all horrors beyond your wildest dreams.
Forth, last time I checked - if you eat a lot of meat, cholesterol still blocks your arteries. Heme iron still causes a lot of oxidative stress, aka you age faster. And animals are filled to the brim with antibiotics and hormones and all that good stuff accumulates in the meat, so you get a good juicy concentrated dose.
Fifth, that steak also hurts humans. Nobody in their right mind wants to work in a slaughterhouse, only the most desperate an financially vulnerable choose this field of work and are scared for life afterwords.
All this misery for 15 minute of sensory pleasure. In a time where we have the impossible burger, beyond meat and a plethora of other options, if we want meat without all the suffering and misery.
