Final answer:
It is true that individuals can act deliberately and shrewdly toward a good end or purpose, such as achieving broader public purposes and not just personal gains. Strategic behavior is not inherently self-serving and can be focused on a public interest.
Step-by-step explanation:
The question is asking whether it is possible to act intentionally and astutely for a positive purpose or outcome. The answer to this question is true. Deliberate and shrewd actions can indeed be directed toward good ends.
For example, someone may act strategically by planning a course of action that benefits a community or society (strategic behavior). Actions do not have to be self-serving; they can be geared towards achieving a greater good or public interest (public purposes). This is evident in several areas such as politics, where rational actors may act strategically and shrewdly to accomplish broader public objectives that also align with their personal goals.
