agree or disagree: the only reason a being is deserving of moral consideration is its potential..?

Disagree. What's your potential

I prefer Kants view

I understand what you're saying. What anyone deserves is hard to measure objectively. I think the moral consideration anything or anyone deserves, depends on how deep they can understand morality itself. The deeper their understanding, the more we should expect from them. So I partially agree.

Disagree. That's not morality, that's pragmatism (not the same thing).

For example, killing everyone under six feet tall because you want a better basketball team is effective but not moral.
