Another circ thread, hah.
With a topic like this, there is no good or bad, or right or wrong. It's all down to personal preference and otherwise (should be) left to medical necessities.
If you're talking about Routine Infant Circumcision (RIC), then there are a lot of morals and ethics associated and it could be argued that it's right or wrong. In my opinion, it's wrong, but a lot of people who choose to get circumcised when they're adults would argue that it's right because it would have been easier for them to get circumcised as an infant as opposed to having it done when you're an adult. Personally, I think that's an absurd argument to make when there are a lot of guys who were circumcised as a child who would have loved to be given that choice.
Like I said, RIC is an issue that involves moral and ethics. On the whole, circumcision is based on personal preference. Some will think it's good, others will think it's bad.
