They could I dicate that yes, but you do need to remember that even these cards have positive indications next to the negative. For example the tower indicates that the thing which is falling to ruin is necessary for new growth of the need to tear down your own pride or blockages.
The ten of swords indicates that ruin must occur for success to be a thing. Like the harvest must come to inorder for anew crop to be planted. The Phoenix must burn to be reborn. None of the cards are purely negative or positive in that right and it is better to determine that based on what cards fall with them in order to judge the situation within.
However, i dissagree with a few of them,
The 8 of swords and 5 of cups especially indicate that the misfortune or regret are at the fault of the individual due to fear or mistakes. The 8 of cups can represent both opportunities presenting, but that the individual is unable to make a decisions or from confusion on what is best and would not indicate that another had cursed that individual.
