Locke grew up as an easy-going farmer and his experiences growing up have imprinted on him. As a result, Locke is kind and values life. Later, as a soldier, war convinced Locke that everyone is a resource and gave him a soldier's sense of humor. Because of this, he will look at the world with an analytical mind and will not hesitate to use everyone and everything around him as a resource, while outwardly being sarcastic and easy-going. The two conflicting factors of his life have warped Locke's mind, causing him to be kind, but analytical. To joke around, but to send troops to their death if he believes it a necessity. He also finds it easy to befriend military personnel, but difficult to identify with civilians.

While Locke grew up on a farm and served the Galactic Alliance in a time when battle skills and survival were more important than rigorous formality. he often puts on a professional exterior, especially when dealing with business or military matters. However, sometimes Locke gets tired of being so formal, and will act more relaxed, unprofessional and true to his roots. Locke is fully aware that this is often frowned upon by others, but at times he cannot help himself, and occasionally even finds satisfaction in making those who appreciate formality uncomfortable. While in the company of those he knows well, Locke almost always drops the professional demeanor, as he personally hates it.

A lifetime of facing chaos throughout the galaxy and the influence of Brotherhood elders has warped Locke's beliefs into his own paradigm based on the Final Way. He sees it as a concept to create peace, via an empire that rules across the known universe. Locke believes that the Brotherhood may be the progenitor of such an empire, bringing everlasting order where Palpatine's empire and others have failed. Thus, he strongly believes that the Brotherhood must stand united against outside threats. While he does have his personal differences, he generally believes that the Brotherhood must be united as one whole and will often set aside his differences with those of other clans to bring about what he perceives as the greater good. Even in battle, Locke is hesitant to seek his opponent's death, unless he believes them a serious threat to the Brotherhood, himself, or his clan.

Locke has a strong sense of duty. He takes any role or job he is given within the Brotherhood very seriously, as he has with every military posting throughout his life. Despite this, his perception of what his duty is and what he has been told to do are sometimes different things. He will not hesitate to disobey orders or deviate from a path chosen by others if he feels it is the most responsible thing to do. As such, sometimes Locke takes the right course of action, and other times he can be stubborn and counter-productive.

As a result of becoming Consul and having to re-evaluate his role in the clan and Brotherhood, Locke has broadened his skills and abilities. He has invested time and effort into many areas, but this comes at the cost of not being as specialized as he once was. While he is resourceful and versatile, he has had to shift his role on the battlefield. He has now formulated strategies depending on his situation, and will go for his blaster rifle first and his lightsaber second, depending on what the situation calls for.

After a lifetime of battle, Locke's emotions have hardened to the point where he is numb to the suffering and horrors of war. His use of the Force has further enhanced this, and Locke has embraced it. During intense battles, he willing isolates himself from all emotion, becoming one with his weapon and the Force. This oneness does not come without a price, for it results in Locke becoming cold and distant.
