You have a different sense of the word than I usually have, although I think both of our senses can be found in dictionaries. I think of suffering as evil, not that which causes it.
I'm not finding your sense of the word in dictionaries so far.
So, two meanings: My sense the death caused by the tsunami is an evil. Your sense, such death is not an evil but a murderer is evil. In common use both senses are ubiquitous, and I suspect most of the time this does not cause problems.
But death is not suffering. That is what the survivors experience. How do you use the adjective? Do you apply it to emotions? Inanimate objects? Animals? Normally, we apply it to intelligent beings that we empathize with. People can be "evil", not rocks or trees or suffering. Suffering may be undesirable and unnecessary, but it is never "evil".
So-called "primitive" peoples have far more sophisticated notions than that. "Animism" (the word usually used to define the "religious" ideas in such cultures) is widely misunderstood as being much like classical polytheism, with the world populated with all sorts of gods. Classical polytheism (of the Homeric sort where gods and goddesses actively interfere in human battles) was mainly a cultural trait of Indo-European language speaking cultures, and by no means universal.
I wonder if animism is more widely misunderstood by ordinary folks or by those who tend to over-intellectualize it. There is a very strong tendency in us to personify everything, especially including forces of nature. We see ourselves in everything, because the world is only meaningful insofar as it relates to experience. The Indo-Europeans were not so different from other cultural groups that existed in their time. Their cosmology, including their views of gods, was roughly the same. Inanimate forces were controlled by intelligent beings such as themselves, and they could manipulate those beings through pleading, cajoling, and contractual offers (e.g. offering exclusive rights to being worshiped in exchange for favors).
You live in Asia, and it is full of people who believe in gods that are little different from the Indo-European ones. Older, more sophisticated people tend to take a less anthropomorphic view of gods, but they still view them as external forces, even if they all ultimately manifest the same being. Monistic philosophy was never exclusive to Eastern religions.
Don't they say that it began in the early times when gods dwelt with them?
Who are "they", and how would "they" know anything more than you or I about it?
