Am I evil for not wanting my sister to attend my graduation ceremony?

I have elder sister who is in her 30s and she's very toxic and loves to create problems and play the victim. She always targets important days like my birthdays, exams and any day any friend of mine visits. She will create an argument with my mom for no reason and as my mom is a heart patient. She gets sick and I get stressed and sometimes it gets worse and I just cry. Although my sister has a nasty personality, she dresses traditionally thus is very accepted by our community and everyone overlooks her evil personality and actually always treat me like I'm cinderella's evil sister. Thus I no longer celebrate my birthdays nor invite anyone over. My graduation is next week and I told mom that I didn't want my sister to attend but then she started preaching me that's she's my family and what will people think of me. But I just want to enjoy that day without drama and crying, I'm really tired of my sister.

Well, to answer your question, this wouldn't mean that you're evil.

Do you think I'm being selfish for not wanting her to attend?

I have no idea why you'd even consider inviting a 30 year old adult sister who you don't particularly get on with to your graduation. My siblings didn't come to mine and I like them!

I am literally going through the same thing. My sister is in her 30s and my grad is in september. We have a small family and I haven't told my mum or my aunt the date yet because I know my sister will just show up. I've been so anxious. Hope you figure out what to do

How will she get a ticket if you don;t give her one? She won't be allowed in ..

That doesn't always apply, I wish it did.

Some venues have appallingly low security and don't check.
Or permit tickets to be sold on the door.
A few institutions in England & Northern Ireland have a horrifying tradition of employing multiple cruel or corrupt lecturers who are in the habit of leaking graduation dates to the relatives/former partners of estranged students who have fled abuse.

This is a serious security concern for very vulnerable estranged students who have to keep a low profile and ensure that their contact info & photos remain private.
Particularly survivors of honour abuse, sexual violence or hate crime.

I always advise them not to book graduation ceremonies & ensure that they as many people as possible at uni know that they won't be attending.
This is what I have done my entire uni life.
Alas, almost all the graduation ceremonies that I avoided were attended by the very bad apples and their clique of scumbags that I will avoid like the plague for all eternity.
I doubt that they spent any more on graduation ceremony tickets than I did.

P.S Sorry for derailing your thread OP.

That is truly shocking - can't those lecturers be reported for breaking safeguarding rules?
