I don't know what you mean "right and wrong". Science is the most general and effective means known to discover the way the world is. Technology (e.g. making antibiotics to cure diseases) is something else - it is there that the value judgments come in, because the same scientific finding (e.g. that compound X kills’ microorganism Y) supports at least two technologies. Either: kill Y by exposing them to X, or: keep Y alive by preventing them from being exposed to X. This is why science is morally neutral.
