A wolf has no moral agency and therefore can't be held accountable for its actions. It makes no sense to compare them to humans.

For the same reason that we now consider murder, assault and other actions that harm people morally wrong. These have also been a part of life ever since humans or other hominids roamed the earth, we just determined that they are morally wrong later on.

I am not aware of any plants that show signs of consciousness or feelings. This would even by disadvantageous to many plants because they "want" parts of them to be eaten to disperse seeds, pollen, etc.

Even if you accept that plants might be conscious and their suffering has to be reduced, you would still harm way fewer plants by eating them directly instead of eating other animals that consume them.
