Whether a sin committed through passion can be mortal?

❌ Objection 1 : It would seem that sin committed through passion cannot be mortal. Because venial sin is condivided with mortal sin. Now sin committed from weakness is venial, since it has in itself a motive for pardon [venia]. Since therefore sin committed through passion is a sin of weakness, it seems that it cannot be mortal.

❌ Objection 2 : Further, the cause is more powerful than its effect. But passion cannot be a mortal sin, for there is no mortal sin in the sensuality, as stated above (Question [74], Article [4]). Therefore a sin committed through passion cannot be mortal.

❌ Objection 3 : Further, passion is a hindrance to reason, as explained above (Articles [1],2). Now it belongs to the reason to turn to God, or to turn away from Him, which is the essence of a mortal sin. Therefore a sin committed through passion cannot be mortal.
