Shouldn’t the readings match the intention of the giver?
No. Such liturgies are called votive masses. The Liturgical Year has its own cycle, even during the week. The offering of the Divine Liturgy for the living or the dead should not control the liturgical theme of the Mass. When a votive Divine Liturgy is celebrated, in addition to the regular parish liturgy, it may be appropriate to take special readings, such as readings for the dead. Examples of such occasions are: funerals, 40 day Liturgies special anniversary or family liturgies.
