It is understandable that clients tend to become emotionally involved in their cases. They will usually want you to treat litigation as a matter of all-out war. You should never succumb, however, to a client's insistence that you treat opposing counsel shabbily. Thus, some clients will be incensed that you have agreed, for example, to opposing counsel's request for an enlargement of time. While you can permissibly make adjustments in the stance and tenor of court papers and other matters so as to accommodate a client's particular ideas, you should never sacrifice professional courtesy just to satisfy a client's lust for hardball tactics.
Clients come and go, but opposing counsel stays around forever.
