Pros and cons of auditing logon

I am running Oracle 8.0.5, and the company wants me to turn on auditing for logon, logoff times for certain users, which I did, and it filled up my system tablespace. I know I can move it, but in reality, I think that auditing is just wasting resources in our situation. Could you perhaps give me the pros/cons of auditing?

There are pros and cons of any action in the databas, and auditing is one of them.

One of the problems with auditing is that it adds overhead to the system. In your case, each logon/logoff action is written to a table somewhere. That table requires space. And as you've already seen, one should move SYS.AUD$ to a different tablespace.

The pros of auditing are that you have reliable, factual information to help resolve problems. You know who did what, and when.
