A single criminal code would not deter someone who violates multiple local and federal laws by intentionally hurting or killing fellow humans. It would do serious damage to our long standing constitutions and way of life. It would also eliminate the backstop that in many cases permits charging by another government when there has been a failure to convict under the primary laws. So no, the proposal would not help and there has been nothing other than reference to other cultures to suggest that it would. Such other cultures make a direct comparison untenable.
We expect laws to deter illegal behavior but in a large and seemingly growing sector of our society, they do not. There are many humans who seem unable to understand or willfully disregard cause and effect. They are apparently unable to control emotional reaction, and our current approach is to mainstream these individuals and pretend that everything will be OK. Shaming, segregation and restraint have been deemed inhumane so those tools are off the table, at a time when law enforcement is under attack and corrections are extremely under funded and were always questionable regarding rehabilitation. I agree that what we are doing is not doing an acceptable job of containing this violence. I disagree that it can be "controlled" by focusing on a specific instrumentality or restrictions that are not effective. Let's encourage useful and respectful dialog on what can be done to reduce violence against other humans, but not waste time on things like assault rifle bans that seem like they should work but have proven ineffective in earlier trials.
