What is the effect of good habit (virtue) and bad habit (vice) on the will?

Good habits, or virtues, strengthen the will by promoting positive behaviors and fostering resilience in decision-making, ultimately leading to greater self-discipline and moral character. Conversely, bad habits, or vices, weaken the will by creating patterns of behavior that are difficult to break, leading to impulsivity and a diminished capacity for self-control. This interplay shapes an individual's ability to make choices aligned with their values and goals. Thus, the cultivation of good habits reinforces the will, while the presence of bad habits undermines it.
