a software tester does not write the code or modify it in any way. That is outside of the functional parameters of testing.

The testers role is to test the software, and document the results of those tests.  There are also related activities such as test plans.

A tester does not decide which bugs to fix.  That is for the Test Manager, Project Manager, Developement Manager, and others to fight about, it is outside of the functional parameters of testing.

A tester does not decide when a project is ready.

A quality assurance person is different, they CAN stop something that does not meet the standard.  This type of testing is done where the failure of a system would be extremely expensive or dangerous.  Food factories, for example, have quality assurance people who make sure nobody will be poisoned by eating the food.  NASA has quality assurance people who try prevent events like the Challenger disaster because they are expensive, and people die.

Maximising quality from the users perspective.  That is the goal of the whole developement team, but that is also the guiding principle of testing.  The users of the system deserve excellence, and anything that falls short of excellence should be reported.   Many will never be fixed, but that is not the only purpose of the bug reports.

The reports are used by everyone in the system, used by customer support personnel to help customers after release, used by senior management to decide if the product is worthy of addition investment, used by developers to fix bugs, used by marketing to decide how to present the product....etc.  The bug reports are the testers product, and their quality is the primary concern of the tester.  If you work at Microsoft, everyone there, including Bill Gates himself could read your bug report.  Never forget that.
