He is determined to be a villain because he is not accustomed or designed as a human to be a lover since no one loves him anymore because of his deformity but later on in the play, we find out that he is just generally hated by everyone in his family (but Clarence until his own death) because of his wicked ways. This makes him seem manipulative, in a way, because he is blaming his deformity for not being a lover and this gives him another chance for the audience to feel sympathy for him. In addition, Richard proves he is evil and is determined to excel in being evil since he can't excel in anything else, by plotting the deaths of both his brothers (Clarence and Edward) and succeeding. When Richard meets his brother, Clarence, who is being arrested for treason, he tells Clarence that Edward's wife is the one who is controlling Edward and making him go mad and that she is the reason for his arrest, when really it is Richards' fault. Richard is lying right to Clarence's face without having any conscience showing how much evil is inside him since a normal person would feel guilt for lying because of their conscience.
The next impression of Richard, chronologically, is that he is charming and nice. When Richard is speaking with Clarence, he puts all his evil thoughts away as if he had never even thought of them before and acts innocent and kind to his older brother. He greets him with "Brother, good day " and "your grace " meaning he is wishing him a great day of well-being. But Richard already knows where Clarence is going and why he's going there because it is his fault Clarence is going to the Tower so, in a way, the well-being is going to Richard instead of Clarence. Furthermore, Richard's kindness shows when he speaks about King Edward's wife and how "noble and fair " she is and she is "never jealous " but there is a sense of Richard saying these words sarcastically about the queen since he did say earlier on in the conversation that it is the queen's fault that King Edward is supposedly ill and poisoned making it the queen's fault that Clarence is going to be imprisoned.
