We are Individually Responsible
It is our personal structure, which defines causally the preferences for our choices. The choice itself is random and thus not caused by any previous event. Thus we as structure are primary cause for our decisions and resulting actions.
Responsibility means feedback of praise or blame to the causing structure.
Despite our random freedom of choice we are individually responsible for our choices and actions, which are influenced by our personal structure. This responsibility is induced by by we as structure being the primary cause and is thus unavoidable.
