Daredevil (Marvel Cinematic Universe)

Matthew "Matt" Murdock is a young man blinded as a boy but gifted with extraordinary senses, who dedicates his life to fight injustice in New York City as a lawyer by day, and by night as a vigilante known as Daredevil.

He is portrayed by Charlie Cox.

Personality
Matt Murdock, for lack of a better term, is complicated. As a child, he felt immense guilt and loss; blaming himself for the death of his father as well as feeling lost after losing his sight. He was both heroic and selfless even as a child, shown best when he saved an elderly man from being hit by a truck, at the cost of his own vision.

Murdock has "daddy issues" with both his actual father Jack and his subsequent father figure Stick, having lost both either to death or from being abandoned. Stick tried to raise him to be coldblooded but suddenly abandoned him when Matt started expressing filial affection; this abandonment and rejection has left Matt with difficulty forging real emotional connections, despite his determination to not let Stick define him.

Matt has a high desire for justice and doing the right thing. He convinced his friend Foggy to quit their work for a firm and work for the common man. During the start of their firm he aimed to help only innocent people.

Unable to allow injustice, he got frustrated when the police or judge failed to help. He decided to work as a vigilante to save people and help where the justice system could not. During this he demonstrated extreme selflessness as he kept risking his life for others, even after he barely made it out of dangerous situations and ended up badly wounded multiple times.

While fighting crime he can be very brutal and heavily injures criminals. However he has avoided killing anyone so far and limits himself to hand to hand combat and sticks to not inflict lethal injuries, even if this results in himself getting injured during fights. He usually attempts to avoid killing anyone, however on occasion (when sufficiently infuriated) he has thrown away his concern for the well-being of his opponents, such as when he threw Semyon off of a rooftop and only checked to see if he was still alive after being asked by Claire Temple. He has also threatened to kill Wilson Fisk, and has acknowledged that he meant it at the time. So far he has been lucky that during these lapses in his sense of morality he has failed to follow through on his intent, however even his temporary willingness to kill still feeds his sense of guilt when he reflects on it.

As a Catholic, Murdock experiences a lot of guilt and soul-searching over his actions when he allows his anger and contempt for violent criminals to cause him to enjoy beating them bloody, and he frequently wonders whether he is doing the right thing in the eyes of God or whether he is allowing evil into his heart. When he feels this way, he approaches his local priest, Father Lantom, for spiritual guidance and advice, however he asks his questions in a roundabout way to conceal his identity as Daredevil, though Lantom has managed to figure out the truth. Either way, Lantom is bound by the seal of confession not to divulge what they discuss.

As Matt met his mentor Stick again he started to doubt his ways and even considered killing Wilson Fisk as he doubted he could stop him any other way. This created an internal struggle as his best friend and others did not want him to act as a vigilante. In the final confrontation against Fisk, he kept true to his vow and ultimately did not kill Fisk.
