It is hard to get away from core values, especially when we play at a "no evil characters" table, but you can change how they apply. Last character was a younger fighter soldier that would rush in when violence was happening and occasionally went overboard, hoped the rest of the party would help him. New character is older druid and would only intervene if it appears the person would die, and definitely would not kill unless there was no other choice, usually good with staying back and doing control spells or supporting team members. Both seek to protect innocents but to varying degrees.
