One of the things that disturbs me about abrahamic religions is that they consider secular movies, music and even job to be sinful. In Islam, music and poetry is considered is haram as they say it takes you away from the rememberance of god. In Christianity, they say that satan makes secular music (ezeikel 28:13) .A song must explicitly have the word Jesus in it to be christian .Whereas Krishna said in Bhagwad Geeta that one has to be poetic or an expert in whatever art he's blessed with. He has to be diligent as well . Aren't good deeds enough for a person to get moksha? A Father would be much happier to see his son progressing and being a good person instead of having a son who keeps telling him yeah I honor you. I respect you. I love you. You're my lord . I mean how can someone forget God. This agenda of abrahamic religions seems absurd to me. (not trying to be condescending)
There are multiple questions here. Is good deeds a step towards Moksha ? Undoubtedly. There are many references which talk about the superexcellence of selfless sacrifice.
Here we find in Gita,
The Supreme Personality of Godhead said: Son of Pṛthā, a transcendentalist engaged in auspicious activities does not meet with destruction either in this world or in the spiritual world; one who does good, My friend, is never overcome by evil.
Again in Gita,
One who is not envious but is a kind friend to all living entities, who does not think himself a proprietor and is free from false ego, who is equal in both happiness and distress, who is tolerant, always satisﬁed, self-controlled, and engaged in devotional service with determination, his mind and intelligence ﬁxed on Me – such a devotee of Mine is very dear to Me.
We find in Srimad Bhagavatam,
It is said that great personalities almost always accept voluntary suffering because of the suffering of people in general. This is considered the highest method of worshiping the Supreme Personality of Godhead, who is present in everyone’s heart.
and in Srimad Bhagavatam,
If one is unhappy to see the distress of other living beings and happy to see their happiness, his religious principles are appreciated as imperishable by exalted persons who are considered pious and benevolent.
Now 2nd question is is serving God necessary for Moksha? Krishna says in the Gita,
I envy no one, nor am I partial to anyone. I am equal to all. But whoever renders service unto Me in devotion is a friend, is in Me, and I am also a friend to him.
and in Gita,
One who engages in full devotional service, unfailing in all circumstances, at once transcends the modes of material nature and thus comes to the level of Brahman.
and Bhagavatam says,
The supreme occupation [dharma] for all humanity is that by which men can attain to loving devotional service unto the transcendent Lord. Such devotional service must be unmotivated and uninterrupted to completely satisfy the self.
What this means is that service to God, spontaneous loving service is a means and ends for Moksha because it is the nature of the jiva to serve Krishna and in that it attains an eternal liberated state, so the service is eternal, joyful and not tiring.
Good deeds to do not lead to moksha. Good deeds lead to the various heavens and rebirth. The Mundaka Upanishad III.ii.3 says (Swami Vivekananda translator):
This Atman is not to be attained by the study of the Vedas, nor by the highest intellect, nor by much learning. Whom the Atman seeks, he gets, the Atman; unto him He discloses His glory.
Doing good works is merely good conduct in this world. Brahma Sutras 3.1.11 (available here - https://www.wisdomlib.org/hinduism/book/brahma-sutras) says:
But (conduct) is merely good and evil work; thus (the sage) Badari (thinks).
What matters is purity of heart. You need to make your heart pure, to want only the Lord.
The 'attitude' a devotee takes to the Lord (friend, servant, lover, etc.) depends upon one's own individual makeup. There is no one attitude in Hinduism.
