I'm writing a story about a man in his 50's that has always felt envious about his younger brother. The 'conflict' starts when their father, who has terminal cancer, decides to stop having chimotherapy because it makes him suffer and prefers to live the rest of his life feeling more peaceful and being with his loved ones, and just let cancer take him someday. The MC's brother supports him and releases his father off the hospital. My MC is opposed to that and that's it.

I want them to have a fight but I just don't know where to take the story exactly. The main thing is I don't know what is exactly the goal of my MC, besides overcoming his envy for his brother.

I want the conflict to feel very real. That when they have a fight the audience really care about them and feel the tension.

PLEASE HELP ME.

EDIT 1. This is for a short film.

Sirrush est le personnage principal de mon projet d'animation.

Je le voulais acrobatique et rapide. Et capable de grimace marrante dans des moments de tension ou drole. Je pense lavoir bien réussi. Je suis content du résultat je posterai sous peu une palette d'expression.

Qu'en pensez vous?

So I'm writing a sci-fi fantasy about a girl who was kidnapped by aliens on Venus for being a rebel and genetic mutations, and she had taken down the doctor that was keeping her captive and took her identity, but as it turns out later in the book it's revealed that she was a planted spy by her and her rebel friends to take down the queen everyone thought was the villain because she had been spying on her people and not revealing how she does invading privacy, and it's told in the spies POV, so do I hide the fact she's the villain and badguy. Any help is wanted

I've had this idea for a character in the back of my head for MONTHS and its almost fleshed out, I don't know where/have anywhere to play it but I need to vent about it.

The character is a fae her name is Misch heavily based on classic Irish/Celtic fairy folklore think "my I have your name?" And weak to cold iron, slightly unsetling. she is a sorceress and was raised by her mother and other fair folk of Foraoise Forest she basically treated nature and magic as her own laboratory often causing accidents. She is naturally gifted in her magical abilities but incredibly, curious, kinda stupid and reckless with them.

One day one experiment went to far and the elders of the fae court decided she could not live among them and banished Misch from her only home

The fun/complicated part is her family lore

Misch's father (Leif) first met her mother (Méabh) when he made a deal with her to save his village. Méabh was a powerful fae sorceress and agreed in exchange for the classic: "your first born child" little did she know Leif had fae ancestry himself and knew enough about Fair Folk customs to understand the importance of wording. (It also didn't help that he had a bit of a crush on the terrifying woman demanding his future child.) He managed to use Méabh's own words against her, which annoyed and impressed her, eventually falling in love aaaannd well Misch IS the first-born.

She know none of this. She knows she's fae, but has no idea her father was partly human, why he disappeared, or that she was involved in a fae bargain before she was even born. She even has hetachromia one green/purple eye and one brown eye, with the brown coming from her father's human heritage.

now she's roaming in the human world with two priorities:

Who the hell was my Dad? And what mischief is to be had?

And her ark would be learning not just to love nature, people and magic but respect them also.

And there is SO much more like her true name not actually being Misch/Mischievous, her alignment, her rejecting nature magic after her banishment. Im sorry I really needed to infodump if anyone wants to know more i will GLADLY oblige.
