The ends do alter the acceptability of the means. E.g. if I offered you the means of “pay money to flip coin to make money as many times as possible” and the numbers involved were $50k if heads, lose $1k if tails and $50 buy in that’s way different if the numbers involved were $1k if heads, lose $50k if tails and $500k buy in.

If you can’t alter your reasoning to include outcomes then you will make poorer decisions.
