I’m a fairly hardcore/radical determinist, and tend to agree that individuals shouldn’t be held morally responsible for actions, any more than a hammer is morally responsible for driving a nail. However, that does not mean people should be free from consequence. There are plenty of reasons - even as a hardcore determinist - to hold people to account for their actions, either as a social corrective mechanism, public safety, deterrent, or personal sanity.
As for getting their actions to align with your morals, that’s a more complicated question that depends on the type of person they are.
