To list mortal sin is not necessary. Each person is to measure by his conscience whether his sin is mortal :
As I have said to you many times. We have an OBLIGATION to formed your conscience:
1783
Conscience must be informed and moral judgment enlightened. A well-formed conscience is upright and truthful. It formulates its judgments according to reason,
in conformity with the true good willed by the wisdom of the Creator.
The education of conscience is indispensable for human beings who are subjected to negative influences and tempted by sin to prefer their own judgment and to reject authoritative teachings.
1784 The education of the conscience is a lifelong task. From the earliest years, it awakens the child to the knowledge and practice of the interior law recognized by conscience. Prudent education teaches virtue; it prevents or cures fear, selfishness and pride, resentment arising from guilt, and feelings of complacency, born of human weakness and faults.
The education of the conscience guarantees freedom and engenders peace of heart.
1785 In the formation of conscience the Word of God is the light for our path,54 we must assimilate it in faith and prayer and put it into practice.
We must also examine our conscience before the Lord’s Cross. We are assisted by the gifts of the Holy Spirit, aided by the witness or advice of others and guided by the authoritative teaching of the Church.55
Now, read carefully so no one turn up like the lovable presidential candidate who happens to be Catholic, John F Kerry who agrees with abortion because his conscience says so
1790 A human being must always obey the certain judgment of his conscience.
If he were deliberately to act against it, he would condemn himself. Yet it can happen that moral conscience remains in ignorance and makes erroneous judgments about acts to be performed or already committed.
Kerry and the likes would like to hold onto this paragraph and do evil things and justify it by saying that they don’t want their conscience condemned them.
Unfortunately for them:
1791
This ignorance can often be imputed to personal responsibility. This is the case when a man **“takes little trouble to find out what is true and good, or when conscience is by degrees almost blinded through the habit of committing sin.”**59 In such cases, **the person is culpable for the evil he commits.
**
1792 Ignorance of Christ and his Gospel, bad example given by others, enslavement to one’s passions,
assertion of a mistaken notion of autonomy of conscience, rejection of the Church’s authority and her teaching, lack of conversion and of charity: these can be at the
source of errors of judgment in moral conduct.
1793 If - on the contrary -** the ignorance is invincible**, or the moral subject is
not responsible for his erroneous judgment, the evil committed by the person cannot be imputed to him. It remains no less an evil, a privation, a disorder.
One must therefore work to correct the errors of moral conscience.
1794 A good and pure conscience is enlightened by true faith, for charity proceeds at the same time
"from a pure heart and a good conscience and sincere faith."60
The more a correct conscience prevails, the more do persons and groups turn aside from blind choice and try to be guided by objective standards of moral conduct.6
