In an emergency, the crew can do pretty much anything that they feel is necessary to get the aircraft safely on the ground. If they end up doing something really bizzare, they may have to justify their actions, but short of that, no one is going to question what they do. As far as what is the penalty for violating a SID or a STAR - it is the same as violating any other portion of an IFR clearance. It can involve a license suspension for a period of time and maybe a fine. In other words, it's something that you really don't want to do. In the real world, a SID or a STAR is something that you frequently get, but ATC often gives you "shortcuts" so as to not require you to fly the entire procedure. For most airplanes, there are very few emergencies which would require the crew to put the aircraft on the ground quickly. I can only think of two or three right off the bat - a fire, a total electrical failure in IFR conditions, and (depending on the type aircraft) perhaps a battery thermal runaway - these are all very rare events, but of course, they can (and have) happened. Are there others? Of course, but most other emergency scenarios give the crews plenty of time to land. It must be remembered, that bad things can happen when flightcrews get rushed.

I listen to the airband frequencies every day in the London Terminal Area, UK.
Fact: 90% of departures are deviated from the SID by controller giving radar vectors within 120 sec. of departure! This is especially true at night time when there isn't much traffic and as soon as an aircraft departs it is almost always given clearance 'route direct to...'.
Fact: Lots of arrivals are deviated from the STAR as they fly in as ATC want to keep all the a/c apart!

SIDs are a way for the controller to talk to you once and not have to talk to you again until you are in Center's airspace and he gives you the freq and says "Good day."
Seriously, I did spend some time making short IFR hops between Houston, Austin and San Antonio and would just be given whatever SID transition was appropriate until told to contact approach at my destination. The same thing was true during the PATCO strike when one could get a clearance based on SIDs, STARs and "tower direct" clearances and never talk to a Center.

The SID for my local airport is the "Tri-cities 4 departure" and it's something like "Fly runway heading, or ATC assigned heading, for vector to assigned route/fix. Maintain 10,000' or assigned lower altitude. Expect clearance to filed altitude 5 minutes after departure." Sort of simplistic, eh? Usually whenever the Delta 737-400 calls clearance it's "Delta 1172, cleared to the Salt Lake City airport as filed, Tri-cities 4 departure, climb maintain 10,000 feet, runway heading, Departure frequency will be 128.75".
