False dichotomy. You can have (many!) things which are more than merely "nice" yet less than the thing you spend all available resources on. To take a well-known public philanthropist as an example, are you seriously claiming that because he does not spend every cent he has eliminating malaria as fast as possible, Bill Gates' view on malaria eradication is that "it's nice that death and suffering are alleviated, but that's all"?

We should probably taboo the word "nice" here; since we seem likely to be operating on different definitions of it. To rephrase my second sentence of this post, then: You can have (many!) things which you hold to be important and work to bring about, but which you do not spend every plausibly-available resource on.

Also, your final sentence is not logically consistent. To show that a particular goal is the most important thing to you, you only need to devote more resources (including time) to it than to any other particular goal. If you allocate 49% of your resources to ending world poverty, 48% to being a billionaire playboy, and 3% to personal/private uses that are not strictly required for either of those goals, that is probably not the most efficient possible manner to allocate your resources, but there is nothing you value more than ending poverty (a major cause of suffering and death) even though it doesn't even consume a majority of your resources. Of course, this assumes that the value of your resources is fixed wherever you spend them; in the real world, the marginal value of your investments (especially in things like medicine) go down the more resources you pump into them in a given time frame; a better use might be to invest a large chunk of your resources into things that generate more resources, while providing as much towards your anti-suffering goals as they can efficiently use at once.
