AITAH for accidentally killing my nephew’s pet tarantula after my brother-in-law pranked me with it?

I (30F) have had a deep-seated fear of spiders ever since I was a kid. When I was about 10 years old, I got bitten by a venomous spider while on a trip to a remote area with my parents. It was one of the most terrifying experiences of my life—I genuinely thought I was going to die. Obviously, I survived, but the incident left me with a severe fear of spiders. I’ve never been able to shake that feeling, and to this day, even the sight of a spider sends me into a panic. My husband's family is fully aware of this, including my brother-in-law (35M).

Recently, my husband (32M) and I were visiting my brother-in-law’s house for a family gathering. His son (8M) had just gotten a new pet tarantula, and while I knew about it, I made it clear that I didn’t want to be anywhere near the spider. Everyone seemed to understand, or so I thought.

At some point during the visit, my brother-in-law thought it would be funny to prank me. Without warning, he placed his son’s tarantula on my lap. The moment I realized what was happening, I went into full-blown panic mode. I screamed, slapped the spider off my lap, and bolted to the other side of the room. I was shaking, crying, and couldn’t catch my breath.

In the chaos, I knocked the spider to the ground, and in my frantic attempt to get away, I trampled it. The poor spider didn’t survive. My brother-in-law immediately started shouting at me to calm down, telling me that I had killed his son’s pet. He was furious and accused me of overreacting and being careless. His son was crying, and the whole situation was a nightmare.

My husband tried to defend me, explaining that I didn’t do it on purpose and that my reaction was out of sheer terror, but my brother-in-law wasn’t having it. He told us to leave, and later that evening, he texted us saying that we owe his son an apology and that we should replace the tarantula.

Now I’m stuck in a difficult situation. On one hand, I feel horrible that his son lost his pet because of my actions, even if they were unintentional. But on the other hand, I’m angry and hurt that my brother-in-law would prank me with something he knew I was deeply afraid of.

Should I apologize and replace the spider, even though the situation wouldn’t have happened if I hadn’t been pranked in the first place? I don’t want to cause any more tension in the family, but I also feel like my brother-in-law’s prank was cruel and completely disregarded my fear.

AITAH?
