Criminal Sentencing Question

[BFritz21]

Say someone has a history of drug use, has attacked cops, gotten DUIs, and has been arrested for a lot of other things.

Then, after a year or so in jail, they attack their brother, stab him twice with a screwdriver, hit him in the head with a frying pan, and choke him, sending him back to jail.

Then, once in jail, they attack guards on multiple occasions, what kind of jail time would they be looking at? Anyone know?

Someone said that he's looking at life, but that seemed ridiculous because he's been in trouble a lot before and never gets much more than a slap on the wrist (besides for the jail time I mentioned).

Anyone have any idea?
