Why does the motive have no effect on the nature of the action? Well, Hitler wanted to acheive racial purity in Germany. A sensible end, but his means were through torture and murder, a barbaric practice any reasonable human can point to as an example of depravity.
The Inquisition felt that they could please God(a decent end) by inflicting horrible punishments on many who were innocent(again, a horrible way to carry out a decent end). However, the very same church that claimed God loved all his children would stop at nothing to punish people they percieved as a threat to the spiritual well being of the whole.
The fact that people think that they can destroy, take advantage of, or in any other way exploit others to achieve their goals is why the ends can never justify the means.
